Tried out the Station/Create and Station/Delete features and had a couple issues.

1: The Artist/Title input box has white on white text, making it pretty hard to use. (I've heard the user/pass inputs also have this issue, but I didn't test that part)
2: The Artist/Title and yes/no dialog buttons are tiny and grouped tightly together, making it very easy to select the wrong one.

As a side note, the "tired" button still exits; it would be great if this sent the 't' key to pianobar...
