Answer to your second question:

I just copy + paste the keyclone folder, and then put a link to that keyclone.exe on my desktop, and name it to what ever it will run.
I got a keyclone setup for 3 hunters(link is named 3 hunters), 5 hunters(link is named 5 hunters), 1 paladin + 3 shamans + mage(link is named main).....See what I did ? And it goes on

Each keyclone is setup for the group I'm going to run with. So how many windows there are, and where and how big. I have been away from MB for 4 months though so maybe there is a better way now.

Btw, I also have a WoW folder for each group, so a smaller window won't corrupt the UI on a char I use for multiple groups.
