I would like the text box that appears when you hover over a territory to display the current unit count on that territory in addition to the territory name, the owner, the max units, etc. Sometimes it can be difficult to read the count on the game board, and it would be nice to have the option of confirming with a hover-over.

This seems like a good idea.  I wonder if Tom goes in to touch this piece of code anyway, is there anything else worth showing on the mouseover?  Continents it's part of?  Factory units that get placed there?

Maybe this would make it too cluttered.

What would be really slick, would be a changing mouse over.  So you mouse-over, and you get the current info (plus unit counts).  Then 5 seconds later, the mouse over shows you all continents the territory is a member of.  Then 5 seconds later it shows you all the factories and the bonuses that deposit units into that territory. 

I have no idea if something like that is possible, or how difficult it would be to do.

changing might be frustrating for some -- what if the only information you want is on the third slide? As the information that is attached to a territory becomes largerk, perhaps a right-click with options for different slides..

+1 for factory units.
