So I should be getting a PiantorFerris Sweep* from Beekeeb in a number of weeks and I thought I would get a head start and plan my layout - or at least one version of it, influenced heavily by Ben Vallack’s video about avoiding press-and-hold mechanics.
Still plenty of fiddling to do. I want to move the WASD-style cursor keys in L3 onto my first three fingers for sure. In fact I’ve already changed it and made room for insert and added shift as a home key mod on the right. God this is addictive.
*ETA: I am, of course, talking about a Ferris Sweep with two thumb keys as depicted in the drawings not a Piantor, which I was also considering. I guess I was swayed by the alliteration.
At a glance, this seems very doable in QMK. It has a whole heck of a lot of functionality built in, and there are user forks that do some stuff differently too. I wouldn’t be too worried about it. Plus the documentation is excellent so if you have questions they can often get answered there
