We use FOP2 for a while and primarily for call transfers.
The list of targets growths and growths.
So far we employ two ways to organize destinations: virtual extensions in Asterisk and Speed Dial FOP2 plug-in.

First one covers too much space on the screen (just like regular extensions) and time-consuming to handle and set-up.
Latter one just gives me long plain list, I can't see the way how to group numbers and/or selectively expand/hide such groups.

Any suggestions for the better way to organize extensive destinations lists to forward?
