(****) tree control replacement for "QuickLaunch" - best tree view for Sharepoint??

Microsoft.SharePoint.Menu provides a tree control replacement for "QuickLaunch" or simply an enhancement to the existing SPS/WSS site navigation.
I've tested and It works well: it show document library or lists under area (or wss) in a tree view, who is dinamic. If you add other list, you can see immediatly in the tree. It also show all documents in a doc library, but I don't know how much this feature can scale when you have a lot of documents. If someone have other info, they're welcomed ;) THX!
