What can I replace it with?
Let's see... In the meantime, I got Milanote and now Obsidian. I hear Joplin is good too, but I haven't used it yet. To be honest, Obsidian is so far a godsend for me.
Any other suggestions or should I just stick with what I have for now?
It looks prettier, but from a quick google search I can see it isn't as good for managing large quantities of academic papers. I've never used it though, so idk
Yeah, it doesn't seem to be able to do the same things your Zotero can do...
