Same firmware, Same software. Nothing has changed. I am not working on the 2s. I have someone that helped but together power budget, hardware architecture, schematic, proof of concept, hardware, etc. Don't worry, I'm not abandoning anything. Runs the same firmware. But I'd be stupid if I weren't working on the 3s, 4s, the 1x, etc. I have to keep moving forward.
I'm working on it, I mentioned this somewhere on the thread.
Already done, it's in the latest beta that's been released and outlined here: https://forum.flirc.tv/index.php?/topic/17557-skipapp-new-wizard-alpha/
Do you mean using the color botton as a shift?
