Heh, the number of points you've probably gotten for that comment, I don't think that it's that unpopular. Win 98 was my jam but it looks hella dated today, but as you said, buttons were clearly marked, but also menus were navigatible via keyboard, soms support for themes and custom coloring, UIs were designable via a GUI builder in VB or Visual Studio using MFC which was very resource friendly compared to using Electron today. Because smartphones and tablets, but even the wide variety of screen sizes also didn't exist so it was a simpler time. I can't believe how much of a step back Electron is for UI creation compared to MFC, but that wasn't cross-platform and usually elements were absolute positioned instead of the relative resizable layout that's required today.
> buttons were clearly marked
Recently some UI ignored my action by clicking an entry in a list from drop down button. It turned out, this drop down button was additionally a normal button if you press it in the center. Awful.
> UI creation compared to MFC
Here I'd prefer Borland with (Pascal) Delphi / C++ Builder.

While it should be beneficial, the reality is awful. E.g. why is the URL input field on [1] so narrow? But if you shrinks the browser window width the text field becomes wide eventually! That's completely against expectations.
