Thanks for the guide.
At the beginning of the guide, you briefly mention the bibnotes plugin:
if only it can eventually match the features of Bibnotes Formatter
Could you explain some more what bibnotes is better at?
I suppose those plugins that don’t tap directly into the Zotero database should work on mobile (provided that the exported zotero records are in your vault). So that would be Bibnotes Formatter (which uses a JSON file exported from Zotero) and Citations (which uses a bibtex file exported by Zotero).
As I think about it, that might actually be a reason to use two plugins: one for mobile and one for desktop.
