I like this app, but you really need to be able to play/pause from any of the tabs. If you're all the way over on the end it can take several seconds to get back to a screen with media controls. This becomes a problem if you need to quickly pause, such as when someone walks up and begins talking to you.
Overall I really love the power user features but the UI on foobar2000 is much better. Only having two tabs and always knowing how many presses of the Back button it takes to close the app is good. Having Artist/Title/Folder/Playlist/etc be buttons on one screen is faster than scrolling through separate tabs for each.
