OK, I think I've got them about where I want them. You can contorl how long they're up, and a bunch of other things like the font. I know it's definitely too obtrusive for some people. The default (for now) is that they are about 20% visible, The bitmap always shows up on the side of the bitmap away form the cursor, They show up for about 2 seconds then disappear. I've got a large font for testing.
I've added the AT, Infantry and AP modifiers. I didn't bother with the Vehicle, Static and Attack (River) modifieres. I don't think that there's a lot of need for them.
Please post comments here or on one of the boards.
