I would very much like to see a small tag indicating paywalled content. It is easy to tell that NYT, WSJ etc are paywalled, and some even allow free viewing, however scientific papers and academia seem to have a higher proportion of such sites. Since this community is pretty STEM centic, a lot of papers, journals, and smaller subscription sites are posted here. If users could simply &quot;tag as paywalled&quot; it would be a timesaver and a rather nice feature. Thanks.
