For the future, power users might desire some more advanced editing options than plain text.
Two obvious candidates would be:
Markdown
WISYWIG
Markdown has the advantage of being simpler to implement and easy to use, and does not take up any real estate in the app. A disadvantage is that "regular" people might have some difficulty with effectively using this. A solution to this would be (partial) tutorials.
WISYWIG is very pretty and people immediately see how it will turn out. However, it is more difficult to implement, and will take up screen space while editing. Also, it might be too powerful a tool for the job.
