New release of Gravity Forms Toolbar includes my contribution of new options to show or hide toolbar menu on admin side and frontend. But, most of the stuff in this and previous release are done by David Decker (more add-ons supported and many other improvements).
Since 1.4.1, plugin supports 5 more add-ons (official and third party), plugin help and documentation is improved and more accessible. If you find any bugs or problems, you can use our or David support forums to report them.
