Hi @Elin, thanks for trying it out! You can change the template for a literature note title in the plugin settings tab, though not all of the properties you mentioned are available at the moment. I’ll put them on the to-do list. (“type of source” can be read from the Zotero export, I believe, though the particular labels probably won’t match your existing set exactly.)
Unfortunately this is pretty far beyond the current powers of the plugin – we don’t keep track of citekey–note relations, beyond the configurable title mapping discussed above. It’d require quite a bit of extra infrastructure to get done, so I probably won’t pursue it unless there is considerable demand.
