I do want that. I also find the current Bank preset very unconfortable when driving. The ideal would be in my view to be able to

1) decide how many banks to have and give them a name (from emplode)
2) do not limit the number of presets per bank
3) chose whether to move to the next bank when pressing NEXT on the last preset of a certain bank, or cycle back to the first preset of that bank.(from emplode)

I also agree in using the knob for some manual frequency navigation. I imagine this: by pressing it once in tuner mode, it could enter a "tuning" state ans stay there for few seconds, as it is now for other sound settings. Knob rotation, in this state, would change the frequency manually. I guess this is what everybody was thinking, but I just wanted to make it explicit :)
