I have some ideas on journalling and tracking here, which may be useful to you. Unfortunately both my ideas aren’t working properly yet. But the concept of using inline dataview fields might help you - it might be a bit more specific compared with using #sleep tags.

- [Discord](https://ideas for using inline dataview fields to track memories associated with people)
I generally use tags to tell me what type of note it is (#journal/daily, #task, #type/podcast/ep, #type/article). Then I can use dataview to select FROM these tags (e.g. from all daily journals, podcast episodes. And call up the relevant field sleep:: 3.
But perhaps you are already ahead of me in this sense! Good luck!
