Hello. I have an org document with many latex snippets for which I use the org latex preview facility. As the document has gotten bigger, any changes requiring a rebuild of all images (e.g. changing `org-format-latex-header') takes longer and longer to the point where it now takes me over an hour to generate all images. Since all images are mutually independent, I was wondering if it's possible to run these tasks in parallel to make use of my multiple CPU cores. If this is not currently possible, what would it take to get this working and how could I help? Thanks Matt
