cool, we'll definitely look into adding more!
as far setting up gestures from scratch: you can use the "reset
profile" action to remove all gesture mappings, so that you can start
from scratch and create your own mappings. (the best way to do this is
probably to create a new profile, make it active, and then use the
"reset active profile action" -- it's under the "profiles" action
group.) this will get you started with a default set of options, and
no gesture mappings set up.
(one thing to note, if you're using this technique, is that auto-save
will be *off* by default for new profiles -- so you may want to turn
that on, or else be sure to explicitly save your profile after you've
set up some gestures!)
