Wasn't aware there was a standard notation, I wanted to use a shape on the keyboard. Thanks for the info, may look at adding those combinations as an option.
Yeah, I was thinking along similar lines as number (2). I think that would also be more obvious when switching between the rows/columns by moving the joystick. Thanks for your suggestions, that's really useful.
Interesting idea, thanks for that. I see what you mean about the joystick use being more intuitive, particularly with the direction. Challenge with that is to highlight the row/column to be moved - it was pretty difficult, technically, to display all of the colours in 3D as it is.
