Enjoy Reading now sits in the Add-on bar by default, but you can move it to the main menu bar if you want to.
Moreover Enjoy Reading now has a keyboard shortcut, just do "control-alt-r" to start it.
Enjoy Reading is heavily based on the old Readability open source bookmarklet.
The only difference for now is that there is no more server calls to the readability server, the add-on embbeds all the logic !
Everything happens on the client side, no more tracking, and way quicker !
Oh and by the way, this add-on is and will stay open-source and free.
