Everytime I think I'm about done with the upgrade to the YT-Designer, or finish off the Ugly Workshop, I think of something else to add, and sit up until the early hours of the morning in photoshop and code adding it.
The YT-Designer has gone from having 64 options, to having 126. The Ugly Workshop by comparison, is far more simplistic, only allowing a body and engines/wings to be combined into one vessel.
