   * Works for self-sharing (user shares note with self)
 - Status: Simplified approach - removed unnecessary Alerts collection code
 
+[2026-01-16 SESSION] FEATURE: Hidden Notes Management
+- Feature Request: Create ability to hide notes from main list, view hidden notes, and unhide them
+- Architecture Decision: Simple boolean flag (hidden) on Notes collection, dedicated view container
+- Implementation:
+  * Added "Hidden Notes" button (id="hiddenNotesBtn", gray-600 style) to notes header
+  * Created hiddenNotesContainer (gray-200 bg, similar layout to notes list)
+  * Added hide button (👁️‍🗨️ icon) to each note card in main list
+    - Click handler: Update note.hidden=true, reload list
+    - Styled: Gray text, hover red, positioned right of title
+  * Added unhide button (👁️ icon) to each hidden note in hidden view
+    - Click handler: Update note.hidden=false, reload both hidden notes and main list
+    - Styled: Gray text, hover green, positioned right of title
+  * Created renderHiddenNotes() function
+    - Filters notesList for n.hidden === true
+    - Renders cards similar to main list but with unhide buttons
+    - Shows empty state "No hidden notes." if none exist
+  * Created showHiddenNotes() view switcher
+    - Hides all other containers, shows hiddenNotesContainer
+    - Calls renderHiddenNotes() to populate
+  * Updated showNotesList() to hide hiddenNotesContainer
+  * Wired button click handlers:
+    - hiddenNotesBtn → showHiddenNotes()
+    - backToNotesFromHiddenBtn → showNotesList()
+  * Updated applySearch() to filter hidden notes from main view (filter: !n.hidden)
+- Features:
+  * Hide any note from main list with single click
+  * Dedicated gray-themed view for organizing hidden notes
+  * Unhide with single click - returns to main list automatically
+  * Maintains existing styling: light blue for shared-with-me notes, green for shared notes
+  * No database schema changes needed - uses existing boolean field
+- Status: Implemented and tested, NOT YET COMMITTED (awaiting user instruction)
+- Database Schema: Notes.hidden (boolean, default false)
+  * No migration needed (handled via PocketBase UI or default values)
+  * Existing notes will have hidden=false implicitly
+- UI State Flow:
+  1. Main list: Shows all notes where !hidden, with hide button on each
+  2. Hidden view: Shows all notes where hidden=true, with unhide button on each
+  3. Clicking hide: Updates note, reloads, stays in main view
+  4. Clicking unhide: Updates note, reloads both views, returns to main
+  5. Search filtering: applySearch() respects hidden flag
+- Next: Await user confirmation to commit
+
