Sorry, I didn't word that very well. I want a button that will automatically include any craft as stock so long as they do not use mod parts (KerbalPaint, FAR, RO, etc), this way I can just see all the craft that will load in stock KSP.
In case it helps, my reason for wanting this is that I am trying to find as many replicas of real missions as I can. The problem is that I then have to look through the mods and see which do not have parts. And then there are mods such as TweakScale, which doesn't technically add new parts, but won't load its craft in stock.
