I spend a lot of time needing to step through/understand someone else's pages/script, and would really like to see a way to immediately link between the HTML on* attributes and the functions that are invoked. I can at least get the function names through the DOM tree sub-tab, but I end up doing global finds to actually get the function being called - especially when someone has overloaded myFunc() with N different parameter options.

Maybe there's a different way to do it, but I haven't found it yet.

chrome lets you see what events are attached to DOM elements. It also lets you add breakpoints to the JS in an onclick="dothis()" so you can just step into it.
