I saw the
Ultimate Hacking Keyboard have a trackball, touchpad and trackpoint module under the thumb.
I think it's an amazing idea. I'm not a big fan of the QMK pointer (it's still cool but...).
So, I wonder if any of you know a "tiny" trackball/touch/pad I could put under my spacebar, near my thumbs so I don't have to move may arms too much to move the pointer.
Thanks in advance !
