 -   :hankey: - Not all ideas are great. These are things I thought might work at one point, but no longer consider worth building. I don't remove such ideas from the repo, because I think all ideas are worth learning from.
 -   :gift: - I'd love to help you build this, consider this like a bounty. You'll get a personal postcard from me for building something on this list.
