Good finds on the subtitles.
I can see your aim w/the design better now, thanks. The bar with audio text may have to be "thicker" though, as some of those track titles are a little wordy. They can be trimmed a bit, though, from the basic description in the nfo file.
In any case, this was my (very much "1.0") audio menu screen.

The lower part was cropped out, as it wasn't very good. I do prefer the "first row" of yours, and understand your ideas about the selection.
The other nice thing about this menu structure you have here: Ease of "re-use" in the other 2 movies, and the consistency factor. Would be nice to see all 3 have something similar, for "familiar" navigation.
Am still curious - did you verify that all tracks are selectable via the menu elements, even though there was mention of the 9 track limitation in the documentation?
Obviously, "all of them on one screen" is ...well... lots of words come to mind. Jarring. Overload. Insane. WTF. ... Again, I did it this way for 2 reasons - one, I was just getting started, and trying to see if it'd even fully function with all 21 tracks (which it does), as well as wanting to start out with "lots of choice" on one screen. More than anything, it was done as a first run to see if it'd work at all with all the tracks. Layout/design was "secondary" to my goal of testing functionality at the time.
All that being said - I'd still be down with helping on the graphics front if you'd like. I could work with the layout ideas you have, as well as the font. It's certainly more readable than the one I was working with (which required layers of various things to "stand out" properly).
There are also a few other things "in the works" which I'll let Harmy speak to...
I can say, that with any luck, these things may be done within about a week, but obviously that depends. Will be very much worth the wait, however.
