It would be very useful for me if, in the map editor->territories->edit screen, similar to the [x,y] button, there were buttons (or drop down?) for  'name' (and maybe max units).

So instead of having to find and click on the territory to edit it, there would be a drop down with the territory names in order to get to and edit it?
If not, I personally am not sure what you mean.

Well, the [x,y] button pops up the x,y coordinates of every territory. I'd like a button that pops up the names of every territory. I've got a map with 4 types of territories, say A, B, C, & D. So every territory is named A1, A2, B1, B2, etc. If I could pop up all the names, I could quickly scan the map and see that I have named everything correctly, but now I have to mouse over each territory separately to get its name to pop up. Maybe this wouldn't be as useful to other people.

Noted, I'll add at some point.
