Summary

WYSIWG editors can be a pain to get the formatting right. Since plane supports markdown, it would useful to have a Markdown or Text view in description fields (or any field that's longer than a single line). This view would just show plain text with no formatting. Toggling back to a "Visual" view would show the text with any rendered formatting.

This would make it much easier to do formatting for anyone familiar with writing Markdown.

Why should this be worked on?

Many existing services support this model, such as github, gitlab, jira. In my experience it is popular among developers (who frequently use task/ticketing software like plane) without taking away from the experience of more typical users.
