Lovely script, very useful, must have!
Just tried this script . A replacement for another script , Town Enhancer , which did much the same but didn't support Depots or Temples.
This has nice clean interface. Like the colour change when resources are adequate for the building's expansion.
Running about 20 scripts and no conflicts so far.
And re the 'negative resources' in a previous review ... that just means you don't have enough to upgrade yet. You are short by the negative amount.
It works but when I ran my mouse over a circle to see how many res I was negative it went behind the building below it so I could see all of the res I was negative.
