[Mod Request] - Collapsed Production Menus

[anansethespider]

In the late game it sometimes feels like it takes a million years to scroll through the entire production menu looking for the thing that I want. One thing that makes it a bit quicker is collapsing the lists I don't want to see (units, buildings, wonders, projects), but it would be better for these menus to start out collapsed, and expand only when I click on them.

Unfortunately, I have no experience modding UI. Could anyone help out?
