Comment on iController

Not as configurable as Barquee...but then, it's free.
Uses a third less cpu power but a third more ram than barquee (roughly). Unlike Barquee, it has to run seperately (launch/quit on it's own ---- so usually have it always on) to iTunes like Quicktunes does, whereas barquee allows plugin use where it only starts up (and shuts down) with itunes, thereby conserving resources.
It also only has basic hotkeys (eg none for altering the rating)......but again, it's free.....whaddya expect?
:D
