As a student I have to read, annotate and tag a lot of PDF’s. So far i still do this in my literature management app but i would love to do this directly in Obsidian. From a research perspective, better native PDF support and in the future reference management options or connectivity to apps like zotero or paperpile would make Obsidian much more useful to me than it already is. I like what they do in Logseq and really hope for a feature like that.
