I have the same feeling now that I had when MC first came with multi-zone (and of course when NetRemote came): Ths is something that's really going to change a lot! There's a new (at least to me) program called iRider that's sort of a shell for Internet Explorer, but it really adds functionality above and beyond what I thought possible and also above and beyond the price (30 dollars).
Instead of having a gazillion windows when surfing (I open new windows for the threads I'm looking at) I now have one window with a thumbnail display in the left part of the browser. If you click on something with the right mouse button, there's another thumbnail surfacing, and it loads the page while you're reading the one you're on. It sounds pretty mundane, but believe me, this is really great! Instead of waiting for pages to open, they open in a nice sequence (I have set it to open two at at time since I have a pathetic ISDN line). You can move up and down with F4 and F2, and close pages with F12.
I still only have the trial version, because I got it two days ago, but this is one program I'll buy!
