Feature Request: Directory auto-refresh and advanced file transfer settings

It would be useful to add file browser features similar to WinSCP:

• automatic refreshing of the current directory with a configurable interval;
• a configurable number of simultaneous transfers and a background transfer queue;
• parallel connections for large file transfers with a configurable size threshold;
• transfer resume support and temporary filenames for incomplete transfers;
• automatic reconnection after connection loss, idle disconnects, or stalled transfers, with configurable retry intervals.

Directory refreshes should preferably preserve the current selection and scroll position.
