Although this pack seems pretty good, I will still look around to see if such thing exists.
I konw that on SP2007, there was one that did this at the Site Collection level - it was based on a SharePoint List (SPListMp). However, it never got ported to later versions of SP, and I don't have the knowledge to do so.
Thanks for your fast reply, and if you ever hear of something like what I'm looking for, please let me know!
Again, big thanks.
