For qwerty crackle I’ve moved snap to the tab key and left control is just back in the bottom left corner of the keyboard (off the layout). Also remove option from 5 and just have that on the bottom modifier row too. I haven’t done much testing in VIM yet, I think I’ll potentially need to move some keys around enter del esc etc to regain some punctuation on the main layer.
Thanks Jack for the interesting layout and comprehensive karabiner config. Great name too btw.
