Backend: - Restore returns each message to its original folder (e.g. Sent/Archive) instead of always the Inbox: new messages.restore_mailbox_id (migration 0010) + restore_thread_job. - Drafts: expunge reconciliation for the Drafts poll (provider.list_uids / _reconcile_drafts) clears phantom "remote" drafts; send + discard drop the mirrored DB row; adopting a remote draft carries its real attachments into the compose flow. - Thread detail/list are folder-aware: individually trashed/spam messages are hidden outside their folder, Trash/Spam show only their own messages, and the mail-list message count matches the view. Frontend: - Thread reading panel: fix newest-first card overlap/spacing (expand-all and single expand), hide Reply/Forward on trashed messages, close the Actions menu on message-body (iframe) clicks, scroll to the inline composer, and prompt Save draft / Discard on the X close. - Composer: remount when switching drafts, dirty-tracking to stop duplicate IMAP mirrors, and close the From/More dropdowns on outside click. - Sidebar: collapse/expand toggle (icons-only ~60px rail) and a log-out icon on Sign out. - Mail-standard printing in a new window with reliable page margins (lib/print.ts).
