Looks great! I'd love to see an option for FR4/PC/POM/some other type of plastic plate. Also split backspace support.
Split backspace support is very difficult when it comes LED's. As with the Slice keyboard, decisions were made about it early on. There are usually a few options but none turn out very well.
1. Allow split backspace but keep the LED in the center causing glare or glow between the keys.
2. Allow split backspace and don't allow backspace to have an LED at all.
3. Allow split backspace but bypass led so when backspace is split, no led will illuminate.
All these options are just really not good in my opinion. SK6812MINI-E leds used in this board are chain connected, so you can't leave one out. There is a way to split 1 led in the chain into 2, but the stabilizers are in the way. I've always tried to restrict the layout when LEDs are involved. With the slice, I feel that it was a good decision to have a really customizable one with no leds and a strict layout with leds.
Perhaps we could have 2 pcb options.
When it comes to case options, were fully making this open source from day 1 so feel free to modify and enjoy however you want. I think we could have an FR4 plate option but as far as case options, we want to leave it as polycarb or aluminum.
