<ref> tags are not only used for footnotes that are literally "references", but for other notes as well. Some find the headline "Reference" confusing then.

Example articles:
* https://en.wikipedia.org/wiki/Interstellar_(film)#cite_ref-interstellar_141-0. When hovering the "[nb 1]", the popup should say "Note" or nothing.
* https://zh.wikipedia.org/wiki/图书馆信息学#cite_ref-1. When hovering the "[註 1]" ("note 1") in the first line, the popup says "Reference", but users expect it to say "Note" or "Comment".
Analysis:
* The enwiki example uses https://en.wikipedia.org/wiki/Template:Refn. It looks like this template contains nothing that allows us to distinguish it from other references.
* The zhwiki example uses https://zh.wikipedia.org/wiki/Template:NoteTag. This template wraps the <ref> in `<span id="noteTag-cite_ref-sup">` (yes, it reuses the same id multiple times). It goes together with https://zh.wikipedia.org/wiki/Template:NoteFoot which wraps the <references> tag in `<div id="references-NoteFoot">`.
Possible ways forward:
* The extension is able to detect a few special reference types, namely "book", "journal", "news", and "web", along with the generic one. We could add a "note" type for the community to use. Note this currently **only** works when the wikitext looks like `<ref><cite class="book">…</cite></ref>`. It's possible to change both examples above to match this requirement, but this is up to the community.
* Ask the communities to change the relevant templates accordingly. Example: `<ref><cite class="web">…</cite></ref>`
* Check if it makes sense to implement auto-detection for some of the most frequently used note templates, if possible. E.g. detect that `id="noteTag-…` when it's used on more than one wiki?
