I find myself clicking to transfer stuff to unload my storage units, especially early in the game. It would be great to have a key (hold F?) to make the storage unit drop all docked objects to the ground.
Also, I like a lot of the endgame storage ideas, but what about a "vending machine"-like device? It could have an input port that "absorbs" a material (like the research aid containers) and "stores" it inside. An output port would then "extrude" the resource when it's requested.
Love the game! Super fun, and my kids love it, too.
