- Fix DM backend ListMessages to use DESC + reverse (match channel handler) - Remove spurious .reverse() from frontend message/conversation stores - Create shared MessageInput component with Slack-style single toolbar row - Add file upload via + button with progress bar and drag-and-drop - Add markdown/rich text toggle with full WYSIWYG block formatting (lists, blockquotes, links, headings, code blocks) - Add frontend+backend security for file uploads (extension + content-type guards)
Both ChatArea and DMChat now detect when you scroll near the top and fetch the next 50 older messages. Scroll position is preserved so you don't lose your place. Works for both server channels and DM conversations.
