In the "edit track information" dialog, there's a location bar with a folder button next to it.  When I click that folder it opens konqueror.  Is there a way to make it open, say, krusader or maybe a terminal instead?  I'm not a big fan of konqueror.  Thanks.

what browser do you have set in amarok config?

well hmm, I thought that was for a web browser and not a file browser.  But apparently changing it to "krusader --left=" (because it's a 2 pane file manager) works.  Thanks.  Is this going to screw things up when amarok tries to open a web browser?

No idea! Why not try it, and report your findings here? If it doesn't work as expected, it might be something the devs could take a look at if you're quick.

Easiest way would be to click "open in external browser" on the "artist" tab (where wiki info is shown).
