Equations are now first-class in the manuscript editor, so you can write mathematics without leaving your draft.

## What's new

- **Inline and block equations** - add an equation inside a sentence, or as a centered display equation on its own line, from the editor toolbar.
- **Type LaTeX or build it visually** - write LaTeX directly (for example `\frac{-b \pm \sqrt{b^2-4ac}}{2a}`) or tap a visual math keyboard for fractions, roots, integrals, sums, and Greek letters. Whichever you prefer.
- **Click to edit** - select any equation to reopen it and make changes, just like the rest of your content.
- **Optional equation numbering** - turn on numbering for a display equation to get (1), (2), and so on down the right margin, renumbered automatically as you add or remove them.
- **Clean export** - equations render crisply on screen and carry through to PDF and print.
