- a system for stricter content moderation, especially something that would automatically delete NSFW/NSFL posts,
- no direct messaging,
- some kind of tool for moderators to efficiently review content,
- multi-layered access to an account to allow for parental control,
- time management tool that would not be based on the client, but with the session duration calculated through interactions.
