# Feature Research

**Domain:** SharePoint Online administration and auditing desktop tool (MSP / IT admin)
**Researched:** 2026-04-02
**Confidence:** MEDIUM (competitive landscape from web sources; no Context7 for SaaS tools; Microsoft docs HIGH confidence)

## Feature Landscape

### Table Stakes (Users Expect These)

Features that IT admins and MSPs assume exist in any SharePoint admin tool. Missing these makes the product feel broken or incomplete.

| Feature | Why Expected | Complexity | Notes |
|---------|--------------|------------|-------|
| Permissions report (site-level) | Every audit tool has this; admins must prove who has access where | MEDIUM | Must show owners, members, guests, external users, and broken inheritance |
| Export to CSV | Standard workflow — admins paste into tickets, compliance reports, Excel | LOW | Already in current app; keep for all reports |
| Multi-site permissions scan | Admins manage dozens of sites; per-site-only scan is unusable at scale | HIGH | Requires batching Graph API calls; throttling management needed |
| Storage metrics per site | Native M365 admin center only shows tenant-level; per-site is expected | MEDIUM | Already in current app; retain and improve |
| Interactive login / Azure AD OAuth | No client secret storage expected; browser-based auth is the norm | MEDIUM | Already implemented; new version adds session caching |
| Site template management | Re-using structure across client sites is a core MSP workflow | MEDIUM | Already in current app; port to C# |
| File search across sites | Finding content across a tenant is a day-1 admin task | MEDIUM | Already in current app; Graph driveItem search |
| Bulk operations (user add/remove, site creation) | Manual one-by-one is unacceptable at MSP scale | HIGH | Already in current app; async required to avoid UI freeze |
| Error reporting (not silent failures) | Admins need to know when scans fail partially | LOW | Current app has 38 silent catch blocks — critical fix |
| Localization (EN + FR) | Already exists; removing it would break existing users | LOW | Key-based translation system already in place |
| Export to interactive HTML | Shareable reports without requiring recipients to have the tool | MEDIUM | Already in current app; retain embedded JS for sorting/filtering |

### Differentiators (Competitive Advantage)

Features that are not universally provided, or are done poorly by competitors, where this tool can create genuine advantage.

| Feature | Value Proposition | Complexity | Notes |
|---------|-------------------|------------|-------|
| Multi-tenant session caching | MSPs switch between 10-30 client tenants daily; re-auth per client wastes 2-3 min each | HIGH | Token cache per tenant profile; MSAL token cache serialization; core MSP differentiator |
| User access export across selected sites | "Show me everything User X can access across these 15 sites" — native M365 can't do this for arbitrary site subsets | HIGH | Requires enumerating group memberships, direct assignments, and inherited access across n sites; high Graph API volume |
| Simplified permissions view (plain language) | Compliance reports today require admins to translate "Contribute" to "can edit files" — untrained staff can't read them | MEDIUM | Jargon-free labels, summary counts, color coding; configurable detail level |
| Storage graph by file type (pie + bar toggle) | Native admin center shows totals only; file-type breakdown identifies what's consuming quota (videos, backups, etc.) | MEDIUM | Requires Graph driveItem enumeration with file extension grouping; recharts-style WPF chart control |
| Duplicate file detection | Reduces storage waste; no native Microsoft tool provides this simply | HIGH | Hash-based (SHA256/MD5) or name+size matching; large tenant = Graph throttling challenge |
| Folder structure provisioning | Create standardized folder trees on new sites from a template — critical for MSPs onboarding clients | MEDIUM | Already in current app; differentiating because competitors (ShareGate) don't focus on this |
| Offline profile / tenant registry | Store tenant URLs, display names, notes locally — instant context switching without re-entering URLs | LOW | JSON-backed, local only — simple but missing from all SaaS tools by design |
| Operation progress and cancellation | SaaS tools run jobs server-side; desktop tool must show real-time progress and allow cancel mid-scan | MEDIUM | CancellationToken throughout async operations; progress reporting via IProgress<T> |

### Anti-Features (Commonly Requested, Often Problematic)

Features that seem valuable but create disproportionate complexity, maintenance burden, or scope creep for this tool's purpose.

| Feature | Why Requested | Why Problematic | Alternative |
|---------|---------------|-----------------|-------------|
| Permission change alerts / real-time monitoring | Admins want to know when permissions change | Requires persistent background service, webhook registration in Azure, certificate lifecycle management — turns a desktop tool into a service | Run scheduled audit scans manually or via Windows Task Scheduler; export diffs between runs |
| Automated remediation (auto-revoke permissions) | "Fix it for me" saves time | One wrong rule destroys access for a client's entire org; liability risk; requires undo capability and audit trail that equals a full compliance system | Surface recommendations, let admin click to apply one at a time |
| SQLite or database storage | Faster queries on large datasets | Adds install dependency, schema migration complexity, and breaks the "single EXE" distribution model | JSON with chunked loading; lazy evaluation; paginated display |
| Cloud sync / shared tenant registry | Team of admins sharing tenant configs | Requires auth system, conflict resolution, server infrastructure — out of scope for local tool | Export/import JSON profiles; share config files manually |
| AI-powered governance recommendations | Microsoft is adding this to native admin center (SharePoint Admin Agent, Copilot-licensed) | Requires Copilot license, Graph calls with high latency, and competes directly with Microsoft's own roadmap | Focus on raw data accuracy and export quality; let Microsoft handle AI summaries |
| Cross-platform (Mac/Linux) support | Some admins use Macs | WPF is Windows-only; rewrite to MAUI/Avalonia is a full project — not justified for current user base | Confirmed out of scope in PROJECT.md |
| Version history management / rollback | Admins sometimes need to see version bloat | Version management is a deep separate problem; Graph API pagination for versions is complex and slow at scale | Surface version storage totals in storage metrics; flag libraries with high version counts |
| SharePoint content migration | Admins ask to move content between tenants or sites | Migration is a fully separate product category (ShareGate, AvePoint); competing here is a multi-year investment | Refer to ShareGate or native SharePoint migration for content moves |

### Dependency Notes

- **Multi-tenant session caching requires Tenant profile registry:** Without a registry of tenant URLs and display names, the session cache has nothing to key against. The tenant profile JSON must exist before any feature can authenticate.
- **User access export requires multi-site permissions scan:** The "all accesses for user X" feature is essentially a filtered multi-site permissions scan. The scanning infrastructure must exist first.
- **Simplified permissions view enhances reports:** This is a presentation layer on top of raw permissions data — it cannot exist without the underlying data model.
- **Storage graph by file type requires Graph driveItem enumeration:** The native Graph storage reports do not include file type breakdown. This requires enumerating files with their extensions, which is a heavier Graph operation than summary-only calls.
- **Duplicate detection requires file enumeration infrastructure:** The file search feature already enumerates files; duplicate detection reuses that path but adds hash computation or name+size matching on top.
- **Bulk operations require cancellation support:** Long-running bulk operations that cannot be cancelled will freeze or force-kill the app. CancellationToken must be threaded through before bulk ops are exposed to users.
- **Duplicate detection conflicts with automated remediation:** Surfacing duplicates is safe; auto-deleting them without undo is not. Keep these concerns separate.

## MVP Definition

### Launch With (v1)

Minimum viable product — sufficient to replace the existing PowerShell tool completely.

- [ ] Tenant profile registry with multi-tenant session caching — without this, no feature works
- [ ] Permissions report (site-level) with CSV + HTML export — core audit use case
- [ ] Storage metrics per site — currently used daily
- [ ] File search across sites — currently used daily
- [ ] Bulk operations (member add, site creation, transfer) with progress + cancel — currently used; async required
- [ ] Site template management — core MSP provisioning workflow
- [ ] Folder structure provisioning — paired with templates
- [ ] Duplicate file detection — currently used for storage cleanup
- [ ] Error reporting (no silent failures) — current app's biggest reliability issue
- [ ] Localization (EN/FR) — existing users depend on this

### Add After Validation (v1.x)

Features to add once core parity is confirmed working.

- [ ] User access export across selected sites — new feature; high value for MSP audits; add once multi-site scan is stable
- [ ] Simplified permissions view (plain language) — presentation enhancement; add after raw data model is solid
- [ ] Storage graph by file type (pie + bar toggle) — visualization enhancement on top of existing storage metrics

### Future Consideration (v2+)

Features to defer until product-market fit is established.

- [ ] Scheduled scan runs via Windows Task Scheduler integration — requires stable CLI/headless mode first
- [ ] Permission comparison between two points in time (diff report) — useful for compliance but requires snapshot storage
- [ ] Export to XLSX (full Excel format, not just CSV) — requested but not critical; CSV opens in Excel adequately

## Feature Prioritization Matrix

| Feature | User Value | Implementation Cost | Priority |
|---------|------------|---------------------|----------|
| Tenant profile registry + session caching | HIGH | MEDIUM | P1 |
| Permissions report (site-level) | HIGH | MEDIUM | P1 |
| Storage metrics per site | HIGH | MEDIUM | P1 |
| File search across sites | HIGH | MEDIUM | P1 |
| Bulk operations with progress/cancel | HIGH | HIGH | P1 |
| Error reporting (no silent failures) | HIGH | LOW | P1 |
| Site template management | HIGH | MEDIUM | P1 |
| Folder structure provisioning | MEDIUM | MEDIUM | P1 |
| Duplicate file detection | MEDIUM | HIGH | P1 |
| Localization (EN/FR) | MEDIUM | LOW | P1 |
| User access export across selected sites | HIGH | HIGH | P2 |
| Simplified permissions view | HIGH | MEDIUM | P2 |
| Storage graph by file type | MEDIUM | MEDIUM | P2 |
| Permission diff / snapshot comparison | MEDIUM | HIGH | P3 |
| XLSX export | LOW | LOW | P3 |
| Scheduled scans (headless/CLI) | LOW | HIGH | P3 |

**Priority key:**
- P1: Must have for v1 launch (parity with existing PowerShell tool)
- P2: Should have — add after v1 validated; new features from PROJECT.md active requirements
- P3: Nice to have, future consideration
