I've finished work on a v2.0-dev branch to add more button functions, resets and sending OctoPrint action commands for pause/resume. Plus changes to how the arbitrary text system works. Hopefully I can get progress monitoring from OctoPrint working too.

I even reduced code size and memory use 👍

It builds, but is completely untested.. I'll test it soon and publish once I have worked the OctoPrint setup out..
