I'd like to use it more often, but it's such a pain to use x.x
I wish they just gave us a field to only type in a name / part of a name and have that person pop up then (even when offline, just shown as offline like they are shown in LS lists).
But no, I have to check like 5 million parameters and if they apply or not just to find someone, so...I use it about once or twice a year and end up still not finding what I was searching for.
They could remove that broken thing for all I care...
