TL;DR
Automatically requested items on space platforms should not stay requested forever at "0" amount.What
Please implement a feature where items that were requested at one point will be removed from that list every so often.You could do it (visually) like in the new labs.

Clarification
Imagine the Utility Science Pack was an item that had been requested in the past and was at 0 (i.e. fully satisfied).Now some countdown is running down, at least a minute, maybe more, maybe user-configurable.
Once that countdown is over, the item is cleared from this list.
Why
The main problem with the current system is that the item that was requested in the past is now unavailable to other space platforms forever*.(*so long as the option "Auto request missing construction materials" is enabled. Sure, you could just disable that option once you are done building. But I feel like it's useful to keep it checked, because in this game you are doing small adjustments every now and again anyway.)
This way the items that were requested automatically in the past can be made available to other platforms again automatically, too.
