Cool. Recent anecdote, I've been looking into ways to setup a semi-complex GUI around an OpenGL canvas. Buttons, menus, styling, scrolling, all that jazz.

I looked into existing options like QT, but found them to be extremely large and full of things I didn't need. I don't blame them for that; they're designed to support a huge range of inputs and have a lot of associated assets. I've also heard that it's possible to build custom 'lite' distributions. But it looked imposing enough to get into as a user that I was about ready to just write buttons and dropdowns and scroll bars in raw OpenGL. It was gonna be messy.

But then, I decided to just use a web browser.

And it was so easy. You can have an OpenGL ES 3 canvas surrounded by UI elements which don't look horrendous, with just an hour or two of setup. The whole thing can respond very gracefully to things like window resizing without much added effort. It is very easy to pass values between the GL context and the UI elements. It is trivial to save/load configurations with any sort of web framework.

Something that could offer similar usability in C definitely sounds exciting. I mean, I complained about QT being bloated, but so is a modern web browser. Most people just happen to already have one pre-configured, and most developers just happen to already be familiar with how one works.
