For example, if I have blocks all around different notes with the tag #technology, is there a way I can have an auto-generated page of all instances of blocks with the #technology tag?
No, at least not at the moment.
The closest workaround I can think of is to click the
Copy search results button in the search pane. It generates a list of links to every note where the tag appears and you can then copy it into a new note.
Thanks, I hope there is some version of this implementation in the future.
It would be nice. You should make a feature request.
