There was a question today on the MathTech discord about using
hypothes.is for note taking. We used to have support for this, but the previous mechnism for it no longer appears to work.
One of my projects still uses it, in theory, by adding the following to the web target in project.ptx:
<stringparams key="html.annotation" value="hypothesis"/>
Building HTML and inspecting source suggests that this is now ignored: I can't find anything in the page source that points to
hypothes.is, so my conclusion is that PreTeXt no longer supports it (as oppposed to a change in their API or something like that).
I'm curious whether there is any value in figuring out how to resurrect it. (If the user base consists of me and one person on Discord, probably not.)
I don't recall if it was intentionally removed, or if it just fell by the wayside during the big push to overhaul HTML (back when we started bundling JS and CSS, etc.)
