Joe,
It comes up from time to time in the forum --

Part of the problem is that RFE's are handled in very esoteric ways at F5, especially since half the company will tell you that iControl isn't officially supported. So getting iControl issues in front of the right audience is a major challenge from a customer standpoint. That being said, YOU have always been an invaluable resource in this forum and for that I am truly grateful! I think there have been many issues that would have been showstoppers without your help in the past.
I think search/filter on the various get_list() methods would be fantastic!
