I would like to make a block/plugin that changes the scroll bars on all pages, base on settings controlled via a dashboard page. I know I could just make the block and stick it in a GlobalArea, but it seems to make more sense to have this plugin controlled through a dashboard page, where when enabled applies itself anytime a page is loaded (as long as not logged in). I've made several plugins, but have yet to make a dashboard page control the plugin. Any insight onto how others have done this or an example to get me started would be very helpful.
