@@ -786,3 +786,14 @@
   - restart realtime socket on new active account token,
   - force refresh chats for both `archived=false` and `archived=true` right after switch.
 - Fixed navigation behavior on account switch to avoid noisy `popBackStack ... not found` and stale restored stack state.
+
+### Step 115 - Settings UI restructured into Telegram-like folders
+- Reworked Settings into a menu-first screen with Telegram-style grouped rows.
+- Added per-item folder pages (subscreens) for:
+  - Account
+  - Chat settings
+  - Privacy
+  - Notifications
+  - Devices
+  - Data/Chat folders/Power/Language placeholders
+- Kept theme logic intact and moved appearance controls into `Chat settings` folder.
