Maybe Kovid could use a colour other than Blue (e.g. Green) if an author has an Evernote URI in the authors.link database column.
If I paste a Note Link from Evernote into a Custom Long Text Column it shows in Green viz:
I'm not 100% sure if the markup in the HTML is generated by calibre or if it comes via the clipboard - all I know is that I certainly don't put it there:
Code:
<div>
<a href="https://www.evernote.com/shard/s105/nl/12032092/53365fed-4bc7-4b19-b5ce-118cc9e56acf" style="color:#69aa35"><b>The Ambassador in China (Hurley) to the Secretary of State | Teaching American History</b></a>
</div>
But I suspect its done by calibre, because if I paste the same link into a .html file all I get is the
https://evernote . . . URI. As you can see it also gets the Note Title - pretty good stuff.
