Why so few upgrades?
Upgrades are designed to help you with Create and Aeronautics related stuff such as making building and maintaining your contraptions more comfortable. Upgrades like simple stat bonuses are not considered (Maybe I will create a separate addon that adds simple stat bonuses as upgrades). Honestly I just wanted to have something like Hover Upgrade to solve a problem of building on an airborne and angled sub-level.
