Memberlist improvement - Search for member, display by group.

For the memberlist, can we get the ability to search the memberlist via username? Also, can we sort the list by groups?

eg: If i wanted to see who were VIPs, i could use a dropdown list to view everyone within the "VIP" group?

this is a basic feature that's been available on software like IPB 1.3.1. as well as being able to type in a username to see if they're registered/on the memberlist.

Just an idea :)

Here's some images for help:

Very basic....

Here's the features from Jcink i'm referring to:

Search for member:

Pretty basic, shouldn't be difficult to implement, but would love to see it done. :)
