Bugs:
1) Clicking on an item in Playing Now brings up the track's context menu, but doesn't select the track until you make the menu go away.
2) Selecting the Display menu item under Controls pops up a sub-menu. If you keep pressing the up/down arrow keys after it's been displayed, it never times out and goes away.
General suggestions:
1) Please make the 'Backspace' key go back a level like it used to.
2) Make the text under the thumbnails and the text in list mode configurable. For example: Artist - Track Title.
3) When searching, allow typing a character to at least move to the associated button, if not select it.
Playing Now Screen Suggestions:
1) Add a 'Clear' button.
2) Remove the useless items from the track context menus: Add, Select, Show Files, Search.
For example:
Selecting Show Files for an item in Playing Now creates a view with a single right-side item named Back with a '<' icon. This seems to suggest clicking on it will go back, but instead the same context menu shows up.
3) Add some useful functions to the same context menu: Remove, Play Next, Move Up, Move Down, Move First, Move Last, ... This is one place where having a menu pop up when you select an item could really be useful if used wisely.
4) Pressing 'Delete' on a right-side item should remove it from the Playing Now list, not pop up a window asking if you'd like to remove the item from your library and/or delete it from your hard drive.
5) Highlight the currently playing track in some more obvious way. The '|>' icon on the right is hard to find. It would be easier if it was on the left.
A final comment:
The Playing Now screen doesn't really show much of the data I'm interested in when I'm listening to music: Track Name, Artist, Album, Time Elapsed/Total Time, Rating, Lyrics, ...
