Great project!<p>I've done some python code optimization recently and I was fairly disappointed in the profiling options; more precisely the profiling visualization options. Standard python provides pstats, which is basic and has an awkward command based GUI. I've tried runsnakerun and snakevis which do provide a nice graphical view but little else.<p>Easy to use, hierarchical list, clear output. I like this. I never used live profiling before and I can already see where it could be super handy.<p>Remarks:<p>-how do I pass arguments to my program. profiling seems to absorb all parameters<p>-Is it possible to access standard input/output when live profiling?<p>-Is it possible to reset the profiling statistics when live profiling? Eg.: I profile a webserver, profile a request, reset stats, profile another request,...<p>-I'd love to see an integration with IPython. Interactive optimization could be great: I profile some code, tweak it, profile again,...
