Robin, I wil definitly try another knob, thanks for the suggestion.
I hope that will increase the user experience ...
... But I do not buy the 'less clicks' argument.
That may be a good design reason when you have separate up-down keys, but with a rotary encoder and a non-sorted menu list is not a big issue.
... also I want to come back on my 'request' for a dual "return>" item, it is more clear for the user that the one-and-only "return>" is always at the bottom of the list (or at the top just like the .. (directory up) in unix directories), so you can very simple turn in the same direction to the 'menu up' item.
Regards, Johan
