I see that the work is an own mod, but for a mod pack it could be included if a developer would program it. Actually i have no idea about programming, so i cannot imagine the workload for such a tool.
But as wee have infomods, which show already differant armor values for all tanks ingame, it should be possible to integrate one value per tank in a database.
For the second, you are right, i saw it first in Quickybabies videos, but i thought more to make it text orientated, like coloured name.
As i said, thought it could improve this very good modpack some day, no need to get into hurry. But as we speak, maybe someone is making it already and it could implemetated in the pack.
