A few notes, maybe known, maybe not:
a) Is there a way to put use text other than "gimp" with the text tool yet? :)
b) xtns->script-fu->web page->alien glow->arrow goes into a tight loop sucking cpu
c) file->save as->png is pretty hit and miss with success, half the time you need to "Ignore" merging visible layers (only one layer) in order to save as a PNG. i haven't tried other formats really
d) tool panel, the eraser has the same tooltip as the paint fuzzy strokes brush
e) gimp is really looking sweet, thank you for the hard work
