I would really appreciate it if browsing in the mpd-database (filesystem) you could update specific parts of the database tree via context-menu to speed up the updating process.
-> Put new stuff via Samba share on your mpd-server with big database
-> Righ click "New Stuff" -> Update
-> Instant access
I think this would simple-to-implement-feature, no other mpd-client has. Requires only some whitespace-handling and update-command-issuing. The path should be known anyway.
