I had a small, private (paid) modification made for me in December of last year which controls the "Show detailed by: Last Click, Member Name" Online User List. With the mod, you can control which user groups have access/permission to the Online List. I was hoping 2.1 would include this by default.
It was made for IPB 2.0.3 and needs updating to work with 2.1. For an experienced modder it should be easy (I'm more a skinner!).
Would anyone fancy updating it on my behalf? We could then make it freely available here, in the Customers' Hints and Tips folder for all to use.
There are similar mods available on Invisionize for example and for older IPB versions, but mine is slightly different and made at the time for my use. No one as yet has made one for 2.1 that I know of.
If you can do it and have mod experience, please PM and let me know.
