I've used BetterSnapTool for some time at it works well. I am guessing BetterTouchTool is from the same person. BTT works well for snapping, but no matter what I set, I can't stop the trackpad from moving the cursor to the wrong spot when typing. The original OSX feature with stopping accidental touches worked. When they removed it, it stopped. I thought this was supposed to be a way to stop it from happening, but even with all the hard press ideas, and thumb ideas, it keeps happening. I'm on a mid 2015 Macbook Pro, with Movave (I need 32-bit programs still) is there something with that setup that prevents it from working? I'm more than willing to pay for it if it works, but so far, it hasn't
Unfortunately BTT can not influence/improve the system's accidental touch recognition.
I'd recommend to send feedback about this to Apple, although it's unlikely they will change this behavior ;-(
