CSS is terrible, no doubt about it, but the problem is exactly that: native GUI frameworks haven't changed in the way they work. Why else do you think electron became popular? Obviously there was reason for it

Well, I do get what he means...

I'm working with heavily themed Qt as a frontend in a rather large project.
Qt Creator (and QML) wasn't available at the start of the project and can't be used, as the code base isn't designed to run on just any machine and is linked to some RT threads.
Would be quite an effort to get the GUI working alone with mock interfaces and things.

So changing something, doing a recompile and see the layout scrambled is quite a downer.

In general I also hate the trend to electron & co "applications", but I still envy a friend of mine working with homepages, when he just needs to refresh the browser to see his changes.
Until I remember working on a homepage 20 years ago and the slight differences between browser were a major pain in the ass.

So, I guess, it's choose your poison...

I haven't really had the opportunity to look into modern C++ GUI Frameworks - and only slightly followed Qt changes, as most of them aren't relevant for the project.
Can anyone recommend something to look into?
Would be nice to have a good starting point, whenever I start something new.
