yt-thumbnail
Design the thumbnail as a concept before you open an editor - the one focal idea, three elements at most, three words at most, and nothing that repeats the title. Lints the plan and writes A/B variants. Use for "thumbnail idea", "design my thumbnail", "my CTR is low", "what should the thumbnail be", or thumbnail A/B testing.
