Command: DROP ALL SHIP COMPONENTS
I think this one is a no brainer. I pick up ship components, I might want to put some here, some there. Who knows.
But sometimes my salvagers need to drop them off. It would be great if I could order a salvage fleet to hit three or four targets, drop everything, then come back for more. Once you wreck a race, for instance, you have dozens of ships all with different components, which means salvaging some ships, and then clicking off each component that you picked up. Worse, once the ship is full, you don't get warning messages or anything-- it just stops giving you minerals and ship components.
This simple command would go a long way to helping.
As a corrolary--
Components salvaged by an empire with grossly superior technology-- ion drives by an ICF drive race, for instance-- should be simply converted to raw resource units directly.
