PDFs workspace
Is there a PDF plug-in that can realize the concept of a workspace, that is, it can save many opened PDFs (such as several core references) as a workspace, and when needed, load this workspace to directly open all you need PDF files (too many projects, a lot of PDFs are painful)!
I too think this would be such a big improvement to zotero. Ideally, I believe an approach where the different tab groups would just auto save the opened/ closed tabs and load the last state when switing would be ideal, instead of the manual-save, "template" approach in the obsidian plugin.
This would probably also much reduce memory usage of zotero. Since one could quickly switch between tab gorups, loading the respective pdfs and closing all other, there would no longer be a need to keep open all pdfs for different projects at once!
