I've noticed that the default text editor is missing a highlight function, instead support suggested diving into the HTML and adding <mark style="background-color: green;">…
Would be really, really nice to have the standard highlighter available in the text editors — great way to mark up a students uploaded text (there is a highlighter in the online PDF form, alas, I have not yet figured out how to change the colour) — I often highlighted in green and yellow to better help students visualize what was good and what might need revision.
Thanks
