From time to time in Star Trek I've seen stuff about some idea, story outline, draft, or eventual novel that was said to have been a "potential episode for the fourth season of Star Trek".
For example in Voyages of the Imagination, it says that Kathleen Sky's novel "Vulcan" started out as a story treatment for a fourth season episode.
Is there any kind of comprehensive list of episode proposals, outlines or ideas for episodes that might've appeared in ST:OS's nonexistent fourth season?

It's only redeeming factor was having the Enterprise tractor beam rip the prison door off. That would've been cool to see. That and not having Spock as "Mr. Roboto".
