For this assignment students had to create an FAQ document as part of a PR kit. The instructor provided comments inside of Canvas in a numbered format. I understand not having a full rich editor but at least offer some things like numbering and/or bolding of text.
It shows up this way in emails, but not in the comments/feedback section.
Hello there, @km3121 ...
It almost sounds like you would like to see some improvements and/or enhancements to assignment feedback via the SpeedGrader. I am not sure if this existing Feature Idea, Rich Text Editor in Speedgrader Comments, might meet your needs or not, but you might want to look through it. If this idea aligns with something you would like to see implemented in Canvas, then you can give it a star rating and also leave a comment on that thread letting Instructure know why this kind of feature would be important to you. (Give examples, too.)
If that Feature Idea isn't exactly what you are looking for, then you can submit a new Feature Idea for folks to evaluate here in the Community. Follow these Guides to get started:
Hopefully these resources will be of some help to you. Please let Community members know if you have any other questions about this...thanks!
