I would like to see the function “Unload & load”.
Reason: The Nozzle temperature can be hold. Its faster and probably even less power consuming.
It can also be named “change” to have a it a bit more precise.
Userflow:
Hit Change.
The ususal Unload procedure starts.,
After succesful unloading, the nozzle temperature does not change and on the screen you can display “insert filament”
and then
[DONE]
[CANCEL]
With done the Load process starts.
