+- Browse remote filesystems in the dual-panel file manager
+- 8 protocols: SSH, SFTP, SMB, WebDAV, S3/S3-compatible, GCS, Azure Blob Storage, NFS
+- Unified connection dialog with protocol tabs (Alt+Left/Right to cycle)
+- Cross-panel copy/move between local and any remote (F5/F6)
+- Remote file editing: F3/F4 downloads to temp, edits locally, uploads on save
+- Create files (Shift+F7) and directories (F7) on remote
+- Delete (F8), rename (Shift+F6) on remote
+- Saved connections: F2 in dialog saves for quick reconnect
+- Background connections with progress display and 30-second timeout
+- Auto-disconnect: Ctrl+T on a remote panel returns to local
+- All protocols shell out to system CLI tools (`ssh`, `sftp`, `smbclient`, `curl`, `aws`, `gcloud`, `az`, `mount`)
+- S3-compatible: MinIO, Backblaze B2, Cloudflare R2, DigitalOcean Spaces via `--endpoint-url`
+- Azure: connection string support, container browsing, Azurite-compatible
+- Debug logging: set `MM_DEBUG=1` for shell command tracing
+
+**Session Persistence (--session)**
+- `middle-manager --session <name>` creates/attaches to persistent tmux sessions
+- Survive terminal disconnects; reattach from any device via SSH
+- Session manager dialog (Ctrl+Y): create, attach, kill sessions
+- Detach with backtick then d (tmux prefix set to `` ` `` to avoid conflicts)
+- Nested session detection prevents tmux-in-tmux issues
+
+**Settings (Shift+F1)**
+- Theme switcher: Far Manager (Classic) and QuestDB Dark
+- QuestDB Dark: deep purple-black backgrounds with rose-pink accents
