I would love to see a SwiftUI-type system implemented at some point. Not in-place of HTML/CSS/JS (that is probably impossible at this point), but I think it would be pretty awesome both to use and to develop with.
Interesting - what is it about SwiftUI that you like?
I feel like it would be easier to keep code looking clean etc. It also would be easier for newer devs to learn/use if they could do something like the right-click style edit that Xcode has.
Your second point sounds like it's already covered. Right click, inspect element, change the styles to whatever you want.
