Hello!
First of all I want to thank for the done work and the enclosed efforts. The add-on is really reputable.

Is it possible to add the following changes into the future versions of Simple Mail?

a) add more columns in address book (for example phone number, address, organization, IM etc)
b) suggest to enter the password each time at the beginning of session or to remember it (by analogy with Thunderbird or Firefox password manager )

Thanks in advance.

PS I'd like to pay your attention that filters do not work correct. Sometimes the message goes to the necessary folder, and sometimes remains in "inbox" . Can you check it up?
