continuing on the mathematical formula theme, and for a complete Sigil novice (well, a software novice, too), I wonder whether you can help me understand the following: I have .xhtml files with lots of formulas that display very well in a browser (e.g. seemonkey), but when I open them in Sigil a lot of the formulas are lost. Is there anything I can do to rectify this problem? Is there a way to make Sigil understand
MathML?
Many thanks!
