Users should be able to customize default presets for gestures. In this photo I want to change the 'click' preset to Mission Control, and invert my zoom. In the current state, I have to completely start over with a custom preset, and manually add these actions; it would be much more convenient if I could just customize this preset. And then have a 'Reset' option to revert it back, or automatically make it a custom preset when adjusted.

I also I can't add zoom gestures to a custom preset as those actions don't exist for custom presets (or maybe I did not see it).

I do have to say, this is a much better UX than the previous version of this app! So, good job it is paying off. I've had far less glitches and a better experience with Options + so far!
