There are a number of suggestions already made about artifact storage, and also the ability to control the order that they are processed.
I suggest an option to upgrade research stations, with each new level allowing it to store additional artifacts. And also suggest a change so that we can control the order the arts are researched.
For the 1st: we could just hit upgrade when we get the credit cap and credits avaiable, similar to the way the planets and other stations operate.
For the 2nd: it could simply be that the arts are research from left to right, top to bottom and we can drag unresearched arts around in the same way we drag the modules around on our ships.
