semantic names for indicator icons...
semantic names for indicator icons For all of the discussion that we had about what kind of icons should and should not be used to indicate what mode the notebook is in, we never went through to make it possible to override it. With this change, it is now possible to override what icons are displayed for Command and Edit Modes. For example, @minrk liked the fighter-jet icon for Command Mode, so he can put this in his custom.css .ipython-command-mode:before { content: "\f0fb"; }
