I really love this idea, came here to propose this.
For me, one of the use cases is that I write big daily notes and I’d much rather separate parts of them to their own files. For example, if I had a conversation with Chris on some topics, it would look like this in the daily note:
- conversation with Chris on our project Zero
** [[Chris]] had idea X, that was connected to [[Y]] we concluded this and that
** our next steps are …
I’d like to create a note "“conversation with Chris on our project Zero” and then later have backlinks to that note, not to the daily note where I have a lot of different topics mixed.
It could easily work with selecting a few lines, clicking a command and then those lines would be moved to a file that’s named as the first line of the selection, with an option to immediately transclude that note, or just automatically doing that.
I see this generally being very useful with any kind of (too) big notes with various topics where you later would love to atomize the notes.
