I should be able to check events on a list, not using 'perf > list'. Do you really think that more kernel developers would use perf more frequently if it had some GUI? I plan to work on a ncurses tool combining aspects of the existing perf tools, integrating them more, like you suggest above, but even having worked on a pygtk tool that is close to the kernel [1], I'm unsure if doing it using gtk or QT would be something that would entice more developers to use it. - Arnaldo [1] http://www.osadl.org/Single-View.111+M52212cb1379.0.html
