Yes. 4W Flight Recorder provides a display for logging messages and 
subsequent handler calls, indented for readability and with relative 
performance metrics.

Double-clicking a line in the display opens the script where that 
handler is defined, and the list can also be saved to a file.

Bonus: messages logged can be filtered, with preset filters for IDE and 
other tools.

You can download 4W Flight Recorder from within the Stacks section of 
LiveNet, or directly at this URL:
