I’m unlikely to use MathJax. But I’m happy to finally be able to write a superscript 2 above an “m” when I need to specify square meters. Nevertheless, here’s a comment from me as an outsider in regard to this feature. The implementation exudes the charm of obsidian. The way Ulysses has implemented it, it is bearish in the best possible way. Here is a video I posted here in the forum almost two years ago. As you can see, a math block does not pop up within the text, but the formula is written in a pop-up and the formula appears exactly where it will remain. It looks much calmer. Furthermore you will see a nifty feature to drag a block into inline text and an inline formula into block formula.
