thanks for sharing your ideas.

1) Added to the ToDo. You can tell Remote Buddy to not display message 
bezels for Bluetooth remotes, btw in Prefs > Hardware > Bluetooth 
Receiver.

2) I'll be thinking about your suggestion. VLC, btw, should enqueue 
the tracks instead of resetting its "playlist".

3) Some users will expect it to go straight back to the "overview 
view", some other users (including you) would prefer it going up a 
filesystem level. It's difficult to find "the right solution" in such 
cases as inevitably, the respectively other group of users will 
complain about the implementation. If you are frequently accessing the 
same directory, the best solution is probably to make it part of a 
customized menu profile.

Best regards, 
Felix
