This is a major redesign a modernization of Sysprof. The core data structures and design are largely the same, but it has been ported to Gtk3 and has lots of additions that should make your profiling experience smoother. Especially for those that are new to profiling. There are some very simple help docs added, but we really need the experts to come in and write some documentation here.
