Hi everyone, I’m glad to share that we’ve just launched text highlight in task descriptions and pages!
Check out the full details here: Make key details pop with text 
highlighting
A few things to know about this first release: it includes one highlight color only. Text color and multiple highlight colors aren’t included yet. Highlights display on web but won’t show on mobile, and editing highlighted text on mobile removes the highlight.
We’re exploring additional highlight colors and refinements and will keep you posted.
Thanks to everyone who voted and supported this launch!
