I do this sort of thing a lot, for a bunch of websites I need to use for work. I make tables sortable with DataTables, add buttons, add important info, fix formatting, make things clickable, move things around, sometimes I add whole new UIs. I mainly use TamperMonkey, as I like the built-in editing more than ViolentMonkey (though it still has its problems).
