There are really millions of small things that I would make in a new desktop OS. First would be to forget the whole idea of resizable windows. Windows should only tile automatically. A tab interface have shown that a simple task bar is just enough. File explorers would have their columns be resized automatically... I can't believe how both OS X and windows 10 still have this wrong. Ultimately I would let applications use hardware directly instead of relying on how the OS do things. This would increase cross compatibility and developer freedom. Good bye Qt and all those horrors of the past. Not to mention how there are millions of small utilities and functionalities like windirstat, foobar2000 that would be ideal to make the OS a little more useful.
