Name: 'Seen It - File Review Tracker'
Author: 'Lazy-Xi'

Track file changes and require review before proceeding.

Seen It is a VS Code extension that helps developers track which files in their workspace have changed and whether those changes have been reviewed. It provides a built-in code review checklist in the VS Code sidebar, ensuring no modified file goes unexamined before committing, opening a PR, or handing off work.

Features

Automatic change detection — Captures file modifications, creations, deletions, and renames in real time via multiple overlapping VS Code APIs, including in-memory dirty-buffer edits before save.
Dual sidebar tree views — "To Review" and "Reviewed" lists with hierarchical directory structure and checkbox-based bulk operations.
Status bar indicator — Shows Seen It: N to review when there are pending files; click to open the output log.
Bulk action commands — Mark All as Reviewed, Approve All, and Approve Reviewed for quick workflow transitions.
Configurable file filtering — Glob-based exclude/include rules with ~170 built-in defaults covering 20+ ecosystems (see src/builtin-excludes.json). Supports user-level and project-level settings.
Persistent state — Review state survives VS Code restarts via workspaceState.
Zero runtime dependencies — Relies only on the VS Code API. The .vsix package stays lightweight.

Usage

Install the extension from a .vsix file or the marketplace.
Open a workspace folder — Seen It activates automatically and starts tracking files.
The sidebar shows two views under the Seen It panel:
- To Review — files that have changed but haven't been reviewed yet.
- Reviewed — files you've marked as reviewed.
Check/uncheck files (or entire directories) to mark them as reviewed.
Use the Actions panel at the bottom for bulk operations.
The status bar shows how many files are still pending review.
