Good. It's always hard to tell if a program will work the same way one 
someone else's machine as it does on my own.

This would be useful to me as well. I'm planning to add it, but I haven't 
gotten around to it yet.

I hadn't really thought too much about this one before, but it could be a 
time saver. I'll think about it some...
