Tiny thing that bugged me: I loaded up something to fabricate, then realised I didn't have my last hackware equipped. I exited the fabricator screen and put it on, and opened the fabricator up again. I had to start from scratch. This led to a full trace and other awkwardness. It would be nice if it didn't remove the schematic like that!
Some nice new additions coming to address this in Alpha 10: Once you load a schematic, it stays there forever, even if you start/finish building something (allowing easier repeat builds). Not only that, but some Fabricators will now be found with schematics
preloaded, allowing you to possibly build something for which you don't even have a schematic yet (especially useful if that happens to be a squad of friends
