UI Suggestion: Option to show pips on building icons for upgrades

[TehManticore]

I find myself clicking in and out of the building screens every economy phase because I forget what's left to get. It'd be really nice if there was a Settings option to show some little pips on the square building icon/button that represent how many of that building's upgrades are left to purchase. Maybe even arrange them on the icon in the same layout as the building screen (2 columns of 3 rows each, a grey square for bought upgrades, yellow for buyable, red for not available, etc). Maybe put a gold border around the whole building icon to show that all of the available upgrades have been bought.

This sort of option would make it easier for experienced players to capture a good overview of the city in a single glance.
