It's not terribly important, especially in the docs.

gedit is a nice little editor and you can do a lot with it, especially with the right plugins. So if you're comfortable with it I wouldn't get too hung up on learning a different editor right now.  I wonder if there's a plugin that will do automatic text wrapping like I was talking about.  I also know a number of people swear by SublimeText, but it's non-free :/
