Trying to add lineheight to the menu....not having much luck. Been to the config.js added this:

Code:
config.extraPlugins = 'font,justify,lineheight,colorbutton,iframe';

{ name: 'styles', items: [ 'Styles', 'Format', 'FontSize', 'lineheight' ] }

config.line_height = "1px;1.1px;1.2px;1.3px;1.4px;1.5px";
But that just made define page editor crash. Removing the plugin modification brought it back.
