Actually, I had tried the Explorer a few weeks ago, but didn't see  
what it was good for until trying it on this class I have with the  
big table. Nice how it breaks the table down, making it relatively  
easy to edit. I'll have to do some more digging on Explorer to see  
what else it's good for. Thanks for the tip.

That is also very useful.

As they say, anything that you don't understand looks like magic, and  
people who can find useful classes in the Squeak class library look  
like magicians to me :-)
