Are you still working on this? I just downloaded it and tested it on my I9300 running CM 11 (Kitkat), and sadly i uninstalled it after I realized it added 3 permanent notifications on my statusbar, and unticking the option of "Show Notifications" in the App Manager renders it unusable, as it won't open anymore. I just installed it again and so far it seems to be normal.. Hide option doesn't work though, it hides it, but i can't bring it back from the notification but it still disables the Back and menu button as if it were open.
Just tested again, opening it from the app drawer, 3 permanent notifications again.. this is bad, I'll uninstall it until it's fixed. Good job though, it would be better if you could add an option to draw while it's hidden, as currently it hides the left side of the screen.
