The current text input is pretty useless, you have to use arrow keys / channel knob (that can't keep up with fast scrolling) and you can only pick from A-Z and 0-9, there is no lower case letters, special characters or even space.
I suggest (open for discussion):
Enable using numpad for direct input 2 = ABC, 1 = special chars stating with "-", 0 = space/0.
Up and down arrow to change input position
Channel knob to scroll through characters
Short press on red to delete character
Long press on red to exit text entry without saving
