We really appreciate that feedback! Thanks @Spooky Squid Games!
I'm glad you are using it and enjoying it!!
We will probably add a few more gestures soon. Working on some big updates for next month. Maybe we'll squeeze in more gestures for that update.
There is 1 hidden gesture that I use all the time: Quick Pinch. If you pinch the screen inward quicky and release, it will zoom out to Fit Canvas To View.
