That's a good idea, but then we should manually compute the equation label, isn't this complex? The fact is that we should use preview-latex as it was designed: wrap the parts of the complete document we want to preview in a preview environment. Why do we extract only the parts we need? My opinion is: preview-latex has a lot of incompatibilities as we saw in the time, using it the way we do now gives us a big burden and (almost) no benefits, so IMHO we have to drop it and create a standard document XOR start to use his real potential. Probably using the full document with preview-latex would make it much slower, making IP unusable on big documents, as it is in TeXmacs. So, my conclusion is: let's drop preview-latex. venom00
