I have now checked your changes. It looks promising. I definitely would wrap everything related to keyaddr in a POD class that features nice constexpr access functions. Also it is definitely going to break existing code. Apart from saving RAM and PROGMEM, such a change would address other aspects related to the way C++ is used in Kaleidoscope. After/while discussing with you, my brain started wandering. This led to a new topic about general improvements of Kaleidoscope. > [@Kaleidoscope's implementation - possible improvements](https://community.keyboard.io/t/kaleidoscopes-implementation-possible-improvements/851): > > @merlin is working on some [interesting ideas](https://community.keyboard.io/t/single-byte-key-addressing-for-boards-with-fewer-than-256-keys/848) to change key positions/addresses from two byte storage to one byte, in order to safe memory. When discussing with him, I was reminded about some related aspects that could be improved in Kaleidoscope. In order not to forget them, I will summarize most of those below, together with ideas how to improve them. Dear developers, please don’t feel offended by me writing this. You have done a great job so far. What I state here are just ideas about how t… --- _[View the full topic](https://community.keyboard.io/t/single-byte-key-addressing-for-boards-with-fewer-than-256-keys/848)._
