I was thinking that if you try to purchase something and don't have enough materials, instead of having to go back to the materials page and buy more then go back to your ship or planet it would be nice if the game would just buy more and make the purchase with one click. this would save the user quite a few page loads as well as a bunch of time.

The would have to be checks to make sure that there is enough room for the new materials and enough credits to buy them as well as the building or ship module, but i think this would be a nice little update.

This has been suggested before.
