X-Tech should have been a vendor rather than a workbench.

As far as I understand, when upgrading using X-Tech, you also spend credits.

But, it feels a little immersion breaking having to pay credits to a workbench, especially if it is one of your own workbenches. I mean, where does the credits go?

Therefore I suggest having a vendor or crew able to perform X-Tech upgrades. If it is a crew, then you can assign them to an outpost or your ship.

Thoughts?
