This UI upgrade is a really nice touch to the tech web but another thing that could take it a bit further is some type of icon on wonders that have already been built or are in the process of being built.

There is nothing more annoying than researching a tech in the hopes of building its wonder only to be disappointed because it was already under construction or has already been built.

I realize there are other ways of discovering this information but for brevity, an icon on the tech web over the wonder would be great!
