I hope this feature will get added to Obsidian at some point.
I was thinking about how this feature could become as useful as possible, and there were a few things that came to mind. If this feature gets implemented, it would be best if several different export options are provided. For example, we can choose to export all of our notes in one PDF, or we can export only notes from specific sections as a PDF. When I say specific sections of our notes, I mean notes that contain a certain tag. For instance, I might pick a specific tag, such as the tag “#focus”, and all of the notes that contain this tag will be grouped and exported as a single PDF. Additionally, it would be useful if we could pick multiple tags to export together in one PDF, since sometimes several tags may be related to one another, so it would be best to export them together.
Also, when exporting based on tags, there should be an option to choose how much of our notes we want to export at a time. We may choose to export a single PDF that contains only notes with a specific tag(s), or we may decide to export all of our notes from that vault as a ZIP file where each of the tags is automatically saved as a separate PDF file.
To add to this, it would be useful if we were able to export our notes not only as PDF, but also in other popular formats such Microsoft Word (.doc and .docx). This is especially helpful because it would give us the flexibility to edit the documents after we export them.
