I am now using Celeste full time at home and it works really well, minus
a few hiccups.  Here are the questions I have:

1) I was wondering if someone had an integrated address book for it.  
2) AutoFilters.  Is there a way to create a rule, such that squeak mail
goes to the squeak folder.
3) unread message highlighting?
4) Is there a way to auto-save after downloading?  I was having trouble
with my image and so I lost about 10 emails
5) nested categories?

Many thanks for the hard work put into Celeste.

cheers,
Rob
