Didn't really call any tool useless, but pointless. As in there are other tools that do things similarly but not the same. But habits are habits and people are not willing to change always, especially if there are a lot of changes to be made, no matter how trivial. Comfort zone is called that for a reason.

Also, not everyone knows how to make something for themself. When I switched full time to Linux we had few options in twin panel file managers which I was use to (Total Commander). None of them worked the way I liked them to. That is to say respected system theme and didn't take a lot of time to refresh directory. So I wrote my own. But it's an ongoing endeavor and I have to say an exhausting one.
