I haven't used kate but does it not have some sort of easy search?
ex. pacman -Qm to list AUR packages; should display the 3/4 pkgs you have installed. Then just search in kate for those 3/4 results?
Alternatively cat & grep in the terminal is pretty straight forward.
That is if it's 3/4 pkgs that are from AUR, but if someone has hundreds installed that is a bigger issue on its own.
