Automatically close TC after BTM finishes

[wanderer]

Remembering an old request of mine from another era, and combining it with this:

03/12/2024 - Added: Background transfer manager: allow to use plus button to manually add "sleep:milliseconds" to the queue (32/64)

Could we also have a "CloseTC" manual command, just like "sleep"? It would just (try to) close TC when everything in BTM has finished and no other window is open (i.,e. "Settings"). Also, could there be something like a "Shutdown" (Windows) and/or "Logoff" commands?
