Some ideas for the references based on the Automatic Backlinks to note plugin:
- allow user to choose Heading for the references (useful if you are writing in different language)
- style the references heading (with the html)
- manually insert the references as plain text (useful for notes that are finished)
And as already mentioned, choosing the citation/reference style (https://discourse.joplinapp.org/t/bibtex-plugin-feature-discussion/).
