There may be a quicker way but you can go to https://archive.org/, put the URL in, and see if you get results.

Just to check, is there a way to find out whether a URL has been archived already and use that rather than create a fresh archive copy every time?

This would be particularly handy when auto-loading a citation and a date comes in looking like "2019-01", translating that to something like "January 2019"—or at any rate something the citation templates recognise—would be very nice!

Shouldn't it really be SVG to allow for scaling?

How about this one?

What's a "marked field" that would be shown full width? Who does the marking?

I like the idea of making the distinction explicit between editing the whole "reference content" and editing individual fields: I'm never quite sure whether those are being kept in sync properly.

I would like the scroll-point for the list of references to be separated from that for the list of fields.

I understand that the {{{df}}} parameter allows one to specify the date, so as to be able to have all dates uniform regardless of how they are entered. Maybe it would be a good idea to be able to find whether this is being used and if so what it is set to?
