It would be very convenient to load/save banks from/to files like we can load/save presets within the editor.
Currently we can only do it from the setlist manager?
Currently, this can be done under the the Controller Backup tab. It’s essentially the same thing as “save bank”, but it is just parked under that tab.
Thank you all
So If I restore a bank saved in a file, the editor automatically loads it in the active bank? (never try!)
Yes, it will load that bank file into the current bank that the MC is in.
Ah ok, thank you!
Perhaps you could give more explicit information above the “restore” button 
Anyway, a similar UI for saving/restoring banks and presets could be more ergonomics.
