Make CodeTree less terrible on the eyes.

codetree-user-styles.css

/**
 * CodeTree default styles are pretty terrible, and the task board
 * is pretty cluttered with lots of useless things.
 *
 * This is a user stylesheet that makes the board pretty clean by
 * removing the sidebar and top navigation.
 *
 * You should apply it to URLs matching `/projects/\w+/board`
 *
 *
 * If you want to get the nav back, just edit the URL so it's
 * `/projects/:id/issues` instead of `/projects/:id/board`
