Feature Request: Progress / Action indicator

[Horgul123]

If you load / unload filament (thanks again for implementing the feature :) ) you klick the icon, it changes color for a second and sets the temperature to 240°. Then it takes a while until somethings happens. If the filament is not inserted correctly, the printer can't extrude anything. But then you don't know if the printer is still working or not.

Idea:
If something is started display an icon (e.g. rotating circle) until the printer tells guppyscreen, that the action is finished.
