I have a suggestion, if you want to hear it.
It might be a good idea to put "Custom Settlements" into the Low Priority catagory and move "Unit Balance" into Medium Priority. Although Custom Settlements in mods are pretty amazing, I am sure most of us who play this mod will be more than happy to keep the standard settlement layouts just with a bit of re-texturing to bring them closer to the appearances of the different races, if it means we have a game that is more balanced sooner. Custom Settlements take an awful lot of time to get right, and although amazing they are often just the icing on top of a very tasty cake. Instead, you could spend that time at a later date, and use time earlier on for improving other, arguably more important, aspects of the mod such as Unit Balance and Bug Fixing.
Tis just a suggestion though
