How can I get the customization found on the Wikipedia screenshot of Amarok @ http://meta.wikimedia.org/wiki/Image:Wpkde_amarok.png ? Specifically:
1) Clear, Undo & Redo buttons moved from top of playlist to bottom-right leaving just Search at the top
2) W wiki in place of Artist

Did not find any right click option nor Configure buttons.

Hi
1. I think you can't. You can add extra buttons to the bottom. Check Settings->Configure Toolbars ...

2. Not possible without changing the source code.

I think the screenshot shown there at wikipedia is a bit old.
