So made some more progress, I was really trying to bust out this menu builder over the weekend but I got hung up on traversing the nested menu tree.

With the tool above I have to reproduce this existing menu system (a little outdated).

Then of course the icons have to be bounded to sub-menu scenes or hardware functions.

Can see my stream of consciousness devlog here.

I will point out, I'm trying to get the major functionality/features built out, doing it in broad strokes so it's not gonna be 100% perfect for now because I really want to get a working camera software and get out there with this camera.
