Del, that tiny little blue frame does not have anywhere to mount a display that won't make it look totally stupid. To have enough size to make it useful for station identification, certainly.
However: You have a DAC and a speaker at hand.
Why not make the station ID audible not visible?!
What about a playlist.m3u structured something like:
# a station
# the next station
Of course, this will make you have to press Prev/Back twice when navigating, that is, until you modify that behaviour too. You might be able to customize vlc shortcuts to process back twice, there might even be some advanced playlist format that allows for this, for all I know there is some "accessibility mode" addons you can load to make it auto-announce the files/streams, I don't know. If it were me, I'd modify the module that processes the button scanning and have it generate two button presses.
Certainly easier than rigging a display to that cute little radio!
