Right now it's not so convenient to switch between upper and lower case letters with the first knob under the display and to choose the character with the fourth knob.
As knob 2 and 3 seem to not have any function assigned while storing/naming rigs and performances I would like to see:
1st knob: Select upper case character (A-Z)
2nd knob: Select lower case character (a-z)
3rd knob: Select number (0-9)
4th knob: Select special character
This would speed up entering of names etc. a lot for me.
