@icedquinn my problem with ergo-split keyboards (based on the whole 1 I've tried) is that you're basically menu-diving every time you need a [ or a ; or a Home/End...
Which, when coding, is all the damn time.
Sadly found that my motivation to retune muscle memory is less than my motivation to plug the old TKL back in.
I'm guessing there is are many layouts that I would end up loving more than standard TKL, but pretty sure I lack the beans for the effort involved in getting there.
