This functionality would be a new setting that can be turned on/off both in the configuration file or via the debugger panel. This would start an event logger that would intercept all event executions and log them with their respective request collection snapshots. This would be sent to the log files and presented in a new panel in the debugger. With this capability the developer will be able to trace requests, events and data changes on ajax enabled applications, or just keep a trace log of executions. Of course, this will make your applciation slower, but hey, its for debugging.
