Backend: enrich message reply data (include created_at and media_files) and ensure chat owners are treated as members; tighten/extend permission checks and message query filters; fix hub routers so moderators/tags routes are resolved before hub detail; accept hub id from request.data in hub permission/tag views; add PostHub serializer and expose hub_detail on posts.
Frontend: update generated API models (postHub, replyTo, members_detail, hub_detail); add hub-related pages/routes and components (HubCard, HubHeader, Tags) and a hub posts feed hook; rework message UI and composer to show richer reply previews (media thumbnails, timestamps), adjust video preload to metadata; add tag selection UI to PostComposer and wire hub tags fetching.
Also: minor UI/UX improvements and generated model exports updated to match backend changes.
Build a members lookup and enrich reaction groups with reactor info; introduce a ReactionPill component that shows a tabbed popover listing who reacted (with ability to remove your own reaction). Move reaction button into the new component and adapt styling/UX.
Fix WebSocket handling in useChatSocket by adding a mounted guard to avoid handling events from torn-down sockets (addresses React StrictMode double-invoke issues) and avoid setting state after unmount.
Prevent duplicate local reaction entries in ChatRoomPage by skipping "added" events when the same user/emoji reaction already exists.
Introduce client-side emoji picker and richer reaction UX, and propagate user IDs for reactions over the WS protocol. Backend: include user_id in reaction events. Frontend: add EmojiPicker component; update useChatSocket types to include user_id; handle "reaction" events in ChatRoomPage to update cached messages (add/remove/switch reactions). Message component: UI overhaul — action menu with slide-out actions, toggle button (⋮→✕), emoji picker trigger, grouped reaction buttons that show counts and indicate "mine" state, and various layout/cleanups. Media: defer video loading by setting preload="none" in ChatMediaGallery, MediaGallery and PostComposer to improve performance.
Introduce a full ChatSettingsModal component for managing group chats (rename/icon upload, add/remove members, toggle moderators, leave/delete) and wire it into ChatRoomPage with a settings button. Add reply preview support end-to-end: new ReplyToSerializer and members_detail in backend serializers, updated frontend Message model (reply_to now contains preview object), and UI changes to Message to render reply excerpts. Improve socket handling to attach reply previews when available. Tweak backend Dockerfile to optionally install Windows/corporate CA bundle only if present and move pip install after copying source. Add Czech translations and small tooling/.claude config enhancements.
