[FEATURE REQUEST] filament color/filament type/nozzle change

[DodoDev42]

planing ahead with the printing queue is great, but what if filament color, filament type or nozzle size change between prints
It would be great to add a color to a print and to get a notification if the color/type/nozzle between prints change, maybe having the possibility to unload the filament after the print automatically.
