This looks really good. It's nice to see some options like this (and slint) appearing for cross-platform desktop GUI. I'm pretty skeptical of "modern" c++ but this looks like a good example of using it where it makes sense.
The data binding looks particularly clever. That's usually the Achilles heel of GUI toolkits (for me at least) and that looks like a clever and novel solution if it works.
