I don't like the idea of CS knowledge gathering. I can see a point separating for Knowledge spending from gathering... but even there, I think it'd be better to just make a global "Tech Unlock" menu that can be accessed at any time, anywhere, rather than attach it to an already multi-function Command Station.
Also, I frequently use multiple labs to gather knowledge faster. Especially when dealing with a Dyson system or Spire Archives: Every second spent gathering there is Bad, so reducing time as much as possible is a good thing.
