I just accidentally clicked the “clear all” on the browser URL and wished that it was a bit harder to click but was still there. If it took three clicks to make happen, its still useful in most circumstances but would drastically drop the mistaken clicks
Anyway, what are your unpopular UI opinions?
A related peeve of mine is stateless URLs. When backend engineers built UIs they were terrible in a lot of ways but the URL would often reflect the state of the UI so you could refresh and get back to the same view. I think web frameworks and people specialising as frontend engineers helped kill this being something that was added as you developed
