> Traditionally, if you wanted to write desktop software, you would use the operating system’s APIs to create a user interface. That’s why Windows apps looked like Windows apps, and Mac apps looked like Mac apps That is oft repeated but having lived through those times that seems just untrue, at least on Windows which was far more dominant than it is today. So many applications, big and small, were using completely custom UIs instead of native things. From WinAmp to Microsoft Office to all of Adobe/Macromedia suites to all cross-platform apps using GTK/Qt (or god forbid, Java). One particular example is the pre-electron Spotify app, which was wonderful small single-exe thing.
