What is the rotation (degree)increment used by foldit?
It is unclear what metric is being used for tweak rotiation, and when used to fine tune, it is not at all repeatable, in part, I believe, to the "gross" movement it chooses for the playerw
Tweak tool should have at least 2 "speeds".
Sometimes we wan to turn helix by 45 deg and it takes alooot of time. Current setting is good for semi-fine tune.
not totally linked but there should be an input box like "rotate X°" so we dont have to manually tweak
