We recently redesigned our equation editor that allows you to insert equations and mathematical notation using a visual editor as well as LaTeX.
How to use it: start a new document or open an existing one. Click Edit at the top of the document and find the \(\mathbf{x^2y}\) button in the toolbar. 

What's new

  1. a brand new look
  2. more mathematical support (we upgraded our KaTeX rendering engine to v. 0.11.1)
  3. a rich toolbar with so many more useful symbols, operators, and letters
  4. quick switch from visual editor (fig \ref{997418}) to LaTeX editor (fig \ref{366376})
  5. ability to display the equation inline, as in \(e=mc^2\) or on a new line, numbered, as below, in Equation 1  (Note: the number will appear when you quit editing)
\[ \Psi = \prod_{n=1}^N\Psi \left (\mathbf{r}_n,s_{zn}, t \right ) \]
