Early update but I had to stop today when I got hung up on recursive traversing lol, I've done it before but was doing it near the end of day/burnt.

This will be a desktop (electron) app.

The "T" is a text box, still have to add that functionality in.

So on the right there will be a nested menu similar to website menus that have nesting.

And the end goal is they produced a nested JSON tree that defines a menu scene, with icon bindings (whether navigating to a sub-menu "clicking in" or running a hardware function)

That's an old JSON structure but it'll work like that.
