When searching something, give us the possibility (f.e. with a toggle button) to show only the paragraph(s) with the search parameter (being anything from tags to checklist items to reminders etc.) and pinning those searches.
Your search and search pinning function is great. One thing that would be even greater would be to enable us to show only the related paragraphs. That would give us the possibility to amazing things like an actual to do list with all and only to do items (instead of whole notes which can be way to large to have a good overview). We could even do to do lists with reminders instead of checkboxes or filter them.
While it would only show us the related paragraphs. It could contain a button, which would open the related note.
