I use Obsidian a lot for extracting notes on engineering articles I read from my Zotero library. That being said, I would love to just be able read and annotate PDFs directly within Obsidian. I know there is the annotation plugin, but that is very limited and doesn’t work well with math text. Also, I cannot draw freehand on the PDF. So, in summary, I want to request a PDF plugin that can allow you to highlight, write notes, draw freehand on the PDF, and then extract the highlights and notes from the PDF into Obsidian.
