Highlight colors and more text formatting.

[Tharon336]

Hi! I am currently self-hosting this project and I am bit frustrated by the minimal text formatting options available. It's usable, I have no BIG complaints besides the highlight option only being yellow. I have a lot of scenarios where I find myself needing more ways to separate/distinguish information in a single 'document' so having at least more options for highlight colors would help a lot.

Thanks in advance!

I would generally recommend using the notice blocks for this purpose rather than colored text.

If you have an example where colored highlights are particularly useful that would be great.
