There is another instance where the ability to update previews would be nice, namely when you change the maths font. (I usually do this in the document preamble.)
I use lualatex for most things but I’d imagine the issue remains for other TeX variants too. Sometimes I don’t get around to changing the math font until later on, and the math previews remain stubbornly in Latin Modern. It would be nice to be able to “View » Regenerate previews” or right-click on a preview and choose a regenerate command. A quick document close and re-open usually fixes it though.
