Data model / backend (migration 1720000000007):
- video_note as a first-class MediaRef kind — round video messages are
explicit, no filename heuristics; mime-validated, own push label.
- Delete for me (message_hidden tombstones) alongside delete-for-everyone;
group owners can moderate-delete any message in their groups.
- Clear history / delete chat per user (cleared_up_to_seq + hidden_at on
conversation_members); deleted chats return on new activity.
- Manual chat folders + per-folder pins (chat_folders, chat_folder_items,
chat_pins; folderId null = "All" tab). Every mutation returns and
broadcasts a full snapshot on the personal channel (folders.update),
syncing devices. New events: message.hidden, conversation.cleared,
conversation.hidden.
- Shared-media listing: GET /conversations/:id/media?tab=media|files|voice.
Web:
- Right-click context menus (shared ContextMenu/ConfirmDialog): messages get
a reactions row + copy/edit/delete; chats get pin/unpin per folder scope,
folder membership, clear, delete; folder tabs get rename/delete.
- Telegram-style editing in the composer (banner + prefill), hover toolbar
removed; delete dialog offers for-me / for-everyone per permissions.
- Folder tabs in the rail with per-folder pinned-first ordering.
- Profile panel (avatar, name, last seen, username, Message button) with
shared media tabs; back arrow on mobile.
- Settings page (avatar, display name edit, theme, log out); contacts as a
separate page; Telegram-style mobile bottom nav (Contacts|Chats|Settings)
with total-unread badge.
- Chat scroll: opens at newest (ResizeObserver keeps bottom pinned while
media loads), per-chat position memory, jump-to-newest button.
- Responsive single-pane layout under 900px.
