Do you have a prose description or repo you'd be interested in sharing? I'm acquainted with Zotero and Omnivore, but I accumulate papers to read much faster than I get through my TBR pile and it's getting pretty unwieldy already.
maybe not that different in terms of functionality.
I have some opinions about ux/ui. I don't understand the graph of obsidian. It's very chaotic. I think the essence of visualization should be simplifying or distilling information, not making things fancy but complex.
