I have two main issues with the MP3 tag editor from Amarok:
1) When using Guess Tags From Filename, you have to do it for each track, it is not possible to make the guess for multiple files.
2) When doing per-track guess, the scheme lineedit
a) does not have focus by default
b) is cleared every time :(
