[Preface: I have zero experience with QMK or the online configurator, just fired it up to have a look around.]
So I'm shortly going to undertake building a Dactyl Manuform (DM) in the largest 5x7 layout. First DIY build, previously I'm using modded TKLs or a Dumang DK6 split board.
Using the very handy 3D generator at
https://dactyl.siskam.link/manuform, I see that there's also an option to include an extra inner column of 3 keys, which is similar to the Ergodox layout. I figure this is handy for extra function keys, trials of various layouts with the Dumang have established that I prefer more keys than less.
Thing is, how does this layout work with the online QMK configurator?
This layout brings the number of columns on each hand to 8 instead of 7, which does not fit any of the pre-fabricated Dactyl layouts (which go up to 5x7). Is it possible to shoehorn this into an existing layout, or does it require bypassing the online configurator and creating something entirely from scratch?
