That's the problem ViolentMonkey and sites like https://greasyfork.org/ are trying to fix but as with many "community contributions" the quality is all over the place
it's super underrated I think, I customize sites quite regularly now to fix things that annoy me! Either to remove things, or to modify content so it takes advantage of a big monitor
As do I. I've never published anything on any community userscript website mostly because I am scratching my own itch(es) and find it suspicious that anyone else would have the same itch and yet want it solved in exactly the same way
There's a lot of people out there. Some might want things to behavior a certain way, but then come across your way and decide it's better, or at least, good enough. Sharing is caring
