Howdy!

First things to say: I have long found this repo (and other stuff, the blog, etc) that you made quite helpful. You have my total respect and thanks!

With that out of the way, I wanted a way to make it easier to "input" the values, e.g when hiding a file or a directory, I thought of having a feature where you could just input it when loading it.

Same with the set_root, I wanted to hide any user, not just the root user.

So I tried my best in doing this contribution which (hopefully) is okay. I did some changes in README files (to reflect what the changes did, and including an example of the change).

If there is any problems, or concerns / comments - please point them out!

Other than that, I do not have very much else to add.

Have a great day!
