Plan new features for the protocol

[fazo96]

Discuss and write down specifics for these features:

• ability to share pages written in markdown, which support versioning and are listable from the user's profile Page system #81
• embed a default board (like "blog") in a user's profile
• trusted profiles list: your trusted profiles' trusted profiles are also marked as trusted
• ability to have URLs pointing to IPFS hashes: the app figures out what that hash is and it shows content appropriately (a post, a comment, a board, a profile, media files)
• global search engine for content (finds users, boards, posts, comments, hashtags, etc based on query)
• hashtags for posts
• chat system, would enable:
  • chatrooms (boards with a chat and no posts)
  • chat + boards (regular boards with a chat)
  • chat should be configurable like boards
  • should use a chain system where every chat message has a link to the previous one and only the latest is exposed
• Access profile from multiple devices
  • best idea is probably have password protected keys and ability to import/export them
  • see Link IPNS ID to username #76
• Outsource administration of boards
• Multimedia
  • images
  • videos
  • audio
  • files and folders
• nested boards, like a forum
• sticky posts
• maybe comment with the board/blog as a parent instead of a post
• password encrypted content
  • see how Laverna does it
• Ability to verify profile with social media, keybase (like keybase)
  • see Link IPNS ID to username #76
• hidden content (requires IPFS to support it)
• code repository hosting, requires:
  • js implementation of git
  • other github-like features
• content versioning: app and protocol should be aware of previous versions of content
