@elegant-eve-85294 I think people would like to see examples of what’s possible, not only to prove them that it is indeed possible, but also how to do it and inspire them, give them ideas.
Also, what I would personally like very much is for CSS classes to be systematically added, because asking for them to be added is time consuming and ineffective. Any element should be up for being customised, and CSS classes are the easiest way for that. And, sometimes, it needs to be smart, like for tabs, having both CSS classes for the tab’s index and the tab’s name would be useful for variety of reasons. Most of the time, a static CSS class that doesn’t change is good enough, though.
