What do you mean by (3) delayed boost?

Imagine holding or double tap on 🔃 button, and you can set when yo boost that note in the future, so like postponed renote. This because usually when a note is relevant gets boosted and renoted by many people at same time, and maybe not seen at all by other users in a different world time-zone. Maybe that could help so the same notes has more visibility for longer time.
