Thanks, slycer. I found the example in "Learning Perl/Tk" that you referenced.

The fileevent method will come in handy.

By the way, this can be a nice tool using the HList widget because you can format list items with different styles.

One of the things that comes to mind is showing errors in bright red or allowing different levels of debug logging to be shown. Or you could have an email if a certain string is found in a log file.

P.S.
My wife hates you now, too.

Please add any ideas you might have about this tool. Thanks.
