perhaps a mod that allowed u to hit a key and toggle the scroll wheel to scroll through the architect tab as to shorten mouse movements.
so you can scroll through the architect and build with just the mouse (i have tab bound to a razer naga)
any ideas welcome too.
Dub's Mint Menus (https://steamcommunity.com/sharedfiles/filedetails/?id=1446523594) might be the thing you need
