Farm and mines filling counter

I am not sure if this was suggested before, at least I could not find it.

Please add a capacity filling counter to farms and mines, it if obvious that this counter exist because at some point they fill up (turn red), and it is adding a line to print it, probably in the farm/mine information tab (?) to show how much it has produced and how close to capacity it is i.e. 3567/4560
This will help to manage resources better and make sure to maximize the production.
I always try to collect every 12 hrs but with everything going on on the game sometimes I am not sure if I collected or not and trying to decide if I should collect and fill my storages and miss on titan or war food/iron loot or wait and let the mine/farm fill up
