In the RIA development I'm doing right now, I'm using the Firebug
console very extensively in order to report all the activity in the
system (Ajax calls, objects creations, UI components events ...).
Things to be reported happen at different levels and the use of
console.group() and console.groupEnd() function are really useful for
this cause they allow to logically group reports based on where they
happened in the system.
The only thing that's missing and that would really really help me
with this is a collapse/expand button on groups, so I could easily
discard any particular group from the console.
When I start-up my application, I can easily have something like 300
lines of output in the console, and when I'm looking for something
specific like a clue that something went wrong, it can be quite
tedious.
Thanks for the excellent work anyway, I wouldn't imagine working
without Firebug.
