I have text snippets formatted with Jira Wiki Markup I use for adding test steps as comments on my Jira tickets. They cover some standard boilerplate, as well as headings and other formatting. However, in the new Issue View, the description and comment fields default to a rich text editor, and I don't see a way to switch back. When I paste my snippets, they get all screwed up. I was able to work around the issue by switching back to the old view, but I expect that's going away soon.
The new rich text editor is nice, but we need an easy way to switch between plain text and rich text.
