New Repo!
This repo is mostly abandoned, and there are a lot of useful updates on https://github.com/Lefuneste83/KLOR. I highly recommend you to use that instead. If for nothing else, use it because of the new LEDs used there, which are the biggest issue you will face with this build.
It says the low profile version is still in beta? I don't need the haptic feedback am I good to go if so?
I imagine it is better to ask there (I am not the owner). Either way, the other repo is better in any way. it has an improved version of 1.3 from this repo, a much revised and superior version of that (1.4), and an in-dev version 1.5. Best ask there in an issue what works best for you.
