Fixed-width font for plain text messages
Feature summary
When displaying received messages (or composing outgoing messages), there does not appear to be a way to use a fixed-width font (useful for ASCII art, tables, etc.).
How would you like it to work?
It would be nice if plain text messages were always displayed with a fixed-width font, but an acceptable fallback would be a user preference to let the user choose a font (and make a fixed-width font available as a choice).
