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.
