I use a Magic Trackpad. Sometimes I go to right click something in Logos (using the two finger click) and my fingers unintentionally slip a little, activating a gesture and causing some unintentional action -- the worst being "close tab."
I know I could assign another way of right-clicking to the Magic Trackpad, like click in the lower left corner, or just use control-click, but I've used the two finger right click for years and it is the best for me.
I would suggest that there be a way to disable gestures via the Preferences -- please.
