I'm looking for an easy way to easily clear one of both of the panes in Picard. Often I want to work on a totally different folder and it alone. Currently I have to quit and restart Picard and then select that folder. I know I can select and remove, but a 'Clear Lists' action on the toolbar would be nice.
http://bugs.musicbrainz.org/ticket/4580 asks for a keyboard shortcut for the same thing.
I'm not sure what's so hard about select all + remove myself...
