Hour Meter is a fantastic idea!
Flux Studio would be a great way to keep a total time count as well as a running count for maintenance.
Right now, I track it all manually on a spreadsheet with the filename of the STL, date, color, print time, and any notes on settings used. It sure would be nice to have some of that taken care of by FS, since it should know print time, although I don't know if the machine itself has a register in the code for tracking time.
The other quirk that really bugs me is that the Load/Unload window closes by itself EVERY time I complete one or the other. Now if I just loaded filament, that's fine. But if I unloaded, obviously I am going to re-load and that window closing by itself is becoming very annoying.
