@michelmar indeed, the `lines` environment has been added to MathLive. Unless I'm mistaken, `gathered` is center-aligned. I couldn't find a "standard" multiline environment that was left-aligned. Another option would be...

Great! Thanks for looking into this. Here’s how I would approach this: - modify `Box.toMarkup()` to add a class (`ML_empty-group`?) if the group is empty and does not contain the...

You’re right, you still need to identify it as an empty group, and `createBox` is the best place for it. I would either create a Box subclass, or you might...

FYI, you might want to consider [1815](https://github.com/arnog/mathlive/issues/1815). The idea is to have an option so that empty groups would be made more prominent (given some width, and a background color)....

I would have expected this to work. However, looking into it, the `` element works with a [limited set of built-in elements](https://html.spec.whatwg.org/multipage/forms.html#category-label), and custom elements that are "[form associated elements](https://html.spec.whatwg.org/multipage/custom-elements.html#form-associated-custom-element)"....

At the moment there are no concrete plans for this, but this is something that could be supported in the future. If someone were interested in contributing this to the...

I think this is a duplicate of #82.

Not response in several weeks. Closing.

In LaTeX, `xyz` is `x` multiplied by `y` multiplied byt `z`. If you want to indicate a single, multi-letter, identifier, you need to wrap it, for example: `const f =...

If you want the subscript to also be considered a single variable, you also need to wrap it, i.e. `\mathrm{R_{A}}`. The corresponding identifier is `R_A`, so use that for assign,...
