After releasing new beta release of MB 0.3 I can tell that configuration of this tab is briliant. One complaint: When you select "show profile tab" for other tab and save this setting, tags are readonly which is correct. But when you come back to configuration of layout, tags are configurable even "show profile tab" is selected

see this screenshot:

Another bug I found is that I can't deselect displayed tabs (artwork, lyrics, other).
I have one suggestion for this. How about splitting other tab to profile and track information tab so people can have these two tabs shown???
I made a picture to imagine what I ment:

or possibly with this description which I think would better :-)

If you select option to show track information tab, Track information panel options (tags) would be configurable, else readonly :-)
what do you think???
