Having cut my programming teeth on a Visual Basic analogue and later Cocoa/AppKit, both of which have a similarly rich roster of widgets, going into front end web development was somewhat shocking and frustrating. Where I would've been writing application logic, I was instead writing common widgets from scratch.

It's hard to believe that this has barely changed in the decade+ since then. The web has grown and matured immensely as a platform, yet it's still necessary to bring in (often heavy) third party libraries to not spend all our time writing basic widgets.

At minimum, browsers should provide basics like recycler views that can satisfy a majority of use cases with a little CSS and act as a foundation for libraries to build upon for the use cases they can't. One shouldn't need to pull in heavy third party code for such common functionality.

That would transform browsers into operating systems.

Negligence is a bliss. They may reach a different solution which others failed to see.

   Open up `designer-qt5`

Ok. we had a disaster before and you witnessed it. Similar disaster is going to happen to this project, why cant you share what you learnt from `designer-qt5` and share it to this project?

What is there to learn ? It's there, it works, lots of UIs are designed on it daily and shipped to happy clients.
