I've brought this up before, but it's been a while and worth another look. There needs to be some kind of filter system or tabs for building planet structures. The higher rank you are, the more disorganized the mess gets. For the artifact page, a text filter like on the planet tab would work wonders. Just type in 'artifact' and se what structures you have can give you an artie boost. For the researched structure build page, tabs so you can split your search between Tacitcal (shields/mines), Stealth, Production, and Other.

One small change that would help out without doing any major recoding at all would be to rename all the Chassis artifacts so they start with "Chassis:" instead of end with it.

something like this?

Sortof. Those are predefined hotlists, I was thinking of a search field like in the planet and artifact windows.
