I was just thinking - I think it would be nice if logs could have a ‘grouping’ option. The grouping option could be turned on in the config. When on, instead of ordering the logs by time, it would order them by level, and then by time. FireBug supports grouping already. Eg:
console.group("DB Logs");
..logs
console.groupEnd();
console.group("Web Logs");
..logs
console.groupEnd();
Maybe also have a group that shows all the logs ordered by time ("All logs"). The inline version of the logs (showInFireBug=false) could take use of some JavaScript to open/close groups, just like behavior FireBug has.
