I clearly disagree to KamilZ delete function request.
It makes no sense, what KamilZ wants is something EmEditor already has – Search + Extract all button.
If Yutaka adds KamilZ feature-request the applications behavior becomes inconsistent, doing the same thing on different ways.
The whole idea behind the dynamic filter is that it is a non-destructive function ( for stuff that must not be manipulated – like important log files …. )

use the search function or simply copy *.* of the filters stuff in a new window.
