I really like the advanced tooltip information provided (like how many beakers a +%Building actually will provide).
I think it would be great if for universities, courthouses and theatres the current number already built (and maybe even in production) could be displayed so you know how many more you got to build till Oxford, the FP or Shakespeares are available.
Maybe something similar could be done for temples/cathedrals. The cathedral tooltips could show how many can be build before more temples are needed and the temple tooltip could say how many cathedrals can be build at the moment.
