Material Sub-Menu
A modding tool to save architecture tab?
For Players
It’s a modding tool, you only need this if another mod has a dependency on it.
For Modder
The function of this mod is, if there’s a stuffable building in dropdown menu, it’ll expand a sub-menu to select material when your mouse on it. So you can organize stuffable buildings into dropdowns, without need to worrying about cannot select their material.
