New Sticky add-on to keep your component always visible

There was question some time ago, how to keep component always visible like in the http://stickyjs.com/

This question seem to be removed from our forum. But, I thought that it should be relative easy to make a Vaadin wrapper for that sticky.js plugin. And, yes it was, but most of time was spent out figuring out how use javascript scrollistener in Vaadin app… Anyway, check an experimental version of my Sticky add-on from Directory: https://vaadin.com/directory#addon/sticky
