Can we have something similar to {fl} toggle but to show/re-hide "hidden" files with one click, so I could extend my Status Bar and make my work easier?
You mean, if you click on the section for hidden files, the filter will disable and show them?
If I'm correct, then I agree, because that's something I try as well from time to time.. o)
Basically yes. I howver rather would like to have separate button for that, but the functionality should be as said: if there are hidden files - i click on icon and filters get disabled and all files listed. I click again, filters reapplied, items hidden again.
If you want buttons for it, they already exist in the default Folder menu.
