I second William's suggestion for this feature. We have built in to our tests to save a copy of the log when the test is done so that we can link to them from a notification email. But that results in 2 copies of the log file. Not to mention that if there is an exception of some kind, that isn't included in the scripted save (because the exception is written after OnStopTest is executed). I've looked at that utility to view the log files, but it's appears to be severely out of date and I don't have the time/capability to modify it to work.
It would be spectacular if TC would natively support outputting the log file in a readable format.
