I've never liked to use the provided ship designs in gal civ, so when they start arriving in force after I research weapons techs, I've been marking them "Obsolete." However, since researching, say, another life support tech basically spawns a new ship design, I can't ever keep these out of my ship list-- I only want to see the ones I've designed! I'd rather not have to keep marking them obsolete with every tech I research.

Also, now is as good a time as any to point out that the 'Core' and 'User' filters don't work-- all of the ships show up regardless of which I click.
