U can do that urself...
Me for example, I prefix everybody with something to group them. Eg
Pilot Steele
Pilot Foxy
Soc Jamhot
Soc KJ
And as they end up in alphabetical order they all get grouped.
My personal wish is, in addition to more space, that it would actually tell you when ur list is full. (Nearly filed a support case trying to add someone from a soc terminal when it was actually full)
Also, the ability to leave someone a message when they are off line.
