With a few hundred LDAP groups, the existing pager beocomes a cumbersome behemoth to negotiate.

Confluence does not remember where I was in the group list browser and goes to the start of the list (chorus of 'Noooo' from my fellow users), can you imagine how much pain is involved in try to delete say a dozed confluence groups with 25pages to wade through after every operation? Gah!

So, some work here would make the group browser usable, currently its there as a last resort due to effort involved in navigating large numbers of LDAP groups. Hitting any of the above points would help reduce the pain.
