I miss functionality to filter files shown in a pane (Total Commander and Midnight Commander both have it).
It is quite important when working on large directories.
It should allow to show only files matching some expression (even simple ones like a*.?yz) would do.
Obviously, there also needs to be a keyboard shortcut to activate/deactivate it.
The pane which is filtered, should be clearly marked as such (an extra color somewhere?), to prevent user mistakes.
Thank you in advance.
