Add chests that can teleport placeable items into your space platform hub, making it easier to create a self sustaining platform.
Providing the player with new tools or adjusting the game interface, without fundamentally changing gameplay.
Augmented or new ways of transporting materials - belts, inserters, pipes!
More than just chests.
For the sake of using this with your other mod Platformer that allows making rail networks in space, you should allow putting rails and trains in the chest.
