There is no need to hide them in fact, it is enough that they are hidden only visually.

Thats exactly the problem.
If they are hidden visually you don't know of what type a file is.
There is of course no other status, they are hidden or not.

But such a possibility has been realized for a long time, but only in the "column" mode.
So it remains to add the usual mode too.
