Thanks for the replies so far
However...
(To put this in context: I have mouse-based RSI, and every unnecessary mouse movement/selection is more annoying than usual. I
really notice the inefficiencies of a program's interface!)
I found the 2 pane split view, and set one to Playing Now, and then made it 1 line long, so I had access to change genre/delete/etc, but the program isn't intelligent enough to scroll the window to the current track, so a change in track doesn't update the display. So no workaround there...
To gain access to the current track's properties, it seems I have to 1) Scroll the left tree pane to "Now Playing" 2) Click on "Now Playing" 3) Move mouse to right pane 4) Edit Properties of track/Delete 5) Click <- Back to restore the previous view. That's alot of convoluted steps.
The Recycle Bin playlist is a good one, but it's not as simple as it could be, as it requires 3 choices to make: Right-click > Send to > Playlist > Recycle Bin.
Is there a global keyboard shortcut that deletes the currently playing track?
