To save time and brain power it would be nice to have independent from project macro and function libraries that you can use In any project. Would save a lot of time. Also would be cool if people had ability to download them from marketplace 🙂

Or the possibility to make unreal packages, like used on the marketplace, by yourself. A collection of reusable asset (like lighting scenes, basic blueprints, skysphere materials and so on).
