Anyone know a plugin or application that emulate the Compiz Annotate funcionality in Gnome 3? Annotate is the plugin that lets you draw on the screen.
It is gnome-shell version 3.6 now in Ubuntu 13.04, But still it has nothing similar to "Annotate" plugin in Gnome 3. I believe, there will be no alternative for that functionality in Gnome. I recommend using Compiz enabled environment like Unity, Or you can customize your own environment using cairo-dock or avant-window-navigator.
