No...that's all web-based stuff.
hmm... is the skin xml something subject to change?if not, why not make a copy of the skin you create and just substitute it everytime you update?
TIP: When Impulse updates, it
WILL overwrite all the original images that you changed. Take a tip
from Snowy and rename all your modified images (I just added [s] to the
end to know they're mine) and then update the changed image names in
the skin.xml and save a copy somewhere, so when Impulse updates, all you
need to do is replace the skin.xml. I just tested it and worked great.
(Impulse updated and it was green again, gah!)
