Dream: Add an omniport and have the option of assigning it to one of the “display spaces” on an LCD. Option to replace or add to the current text displayed there.
Today you can fake this by adding extra text to an onboard footswitch label with a seperator (e.g. Boost - Home) or in the left middle or middle middle displays. But it’s a hack that is hard to manage and is missing all the capabilities of a switch.
This hack would have more space if we could also override the right middle display (perhaps by editing a format string that controls what widgets or text you want to see or not (bank/page number and expression value, I’m talking to you).
