It's not only the users that are frustrated.

Developing a VB app in the 90's was simple; just drag'n'drop components around the place and boom, you're done. There were very little design choices to make, and most of those were about accessibility rather than style. It had to look like a Windows app, and that was it. A developer could (and we did) slap together screens in minutes, and while they would never win any prizes for best-looking application UI, they were instantly usable by users because they all shared a consistent UX.

Making a web app means following a Figma thing where a designer tried a new experiment with some new thing they read about last week, and it kinda looks OK as a static screen design, but has huge problems as a User Interface because users don't understand it (and that's not even considering accessibility). And as a developer it's a pain in the arse to implement; lots of work to work around the standard way of things working because the designer thinks it looks good.

My personal bugbear on this is scroll bars: just leave the fucking scroll bar alone. No, it's not "pretty", but it tells me how far down the page I am and it's useful. Removing it is actively making my life worse. You are spending effort making my life worse. Stop doing that.
