So I should be getting a ~~Piantor~~Ferris 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.
Google Sheets with lots of cell merges. I'll share the template doc when I'm at my computer later. 👍
Perhaps not exactly what you're looking for, but I'd check out keymap-drawer. I've been using this to draw out my keymaps and it's been great!
Oh no that looks gorgeous and very handy (even if I'm more of a Ruby gal).
This is not my tool by the way. Just one I've found. Wanted to make sure I wasn't being given credit when all I did was stumble upon it 😉
Oh no I got what you meant. I appreciate you mentioning it.
I've used QMK configurator to sketch out keymaps before. You can download your keymap as JSON file and later upload it again to make more changes, or save a few different versions. It can even compile your firmware, but I've not used that feature. No programming required if you only use basic QMK features. It supports Piantor with a 3x5 layout: https://config.qmk.fm/#/beekeeb/piantor/LAYOUT_split_3x5_3
