Could you add Fystec hotkeys in the future?
I've installed this addon on my voron 2.4 and it's very useful feature.

looks doable. But I need to take a look. probably won't make it in the next release, which is released in a couple days apparently.

Yes that would be great! I am using these too. I like you klippain very much, it helps a lot of people. I have already donated and will do it again, hope you will go further with this project. Thanks!
