First off, I'd like to say that I love pn! I use it all the time every day. Thanks for such a great tool!
One of the best features is monitoring that a file has changed. It's great for me when I want to keep refreshing a log file. But what would be better is if pn could tail the file and automatically update as the file is udpated, and of course scroll the file.
It would be nice as an option and not as a default option as it could annoy some users.
