Total building count statistic

[Philuminati]

There is one thing with the building statistic that always bothered me: You can see how many e.g. electrical miners you built, and how many you deconstructed, but you can't see of how many miners your current factory is composed. It would be really cool to see the count of all your machines and having some graphs showing you how your factory grew would be nice too. I think it should be easy to add such a feature because of how the statistics work at the moment.

Thank you,
