Hmm, good point. I can understand how that might be confusing.
I don't understand what you're suggesting here?
My general instinct is that paint programs can be better for creating the overall shape of a ship, especially when you want the ship to have nice curves or other shapes that are hard to make with the tools in Cosmoteer. But in terms of specific part types, orientations, and doors, I'm not convinced that a paint program would provide a better interface for doing that detail work than Cosmoteer. I'm happy to be convinced otherwise, however!
Yeah, it's the cleanest I've found, pretty modern feeling. It's still in development though, so it's got some missing features, like previews on new posts, and some bugs.
