Hi 
Ashley!
Working with C2 is much about toggling groups. Would you consider adding groups watcher to the profile tab of debugger? Groups are listed there already, so just some marker to highlight which groups are currently enabled/disabled would be a huge timesaver. Currently we have to use Browser.log which takes time to put in the particular groups, especially if you're searching for the bug in unknown place.
So this could be done with brighting group name or bolding it or even adding some marker like (*) or whatever next to the group name under profile tab.
Let me know if this is something to consider for you or there are some technical difficulties regarding such feature?
Thanks
