From the developer: "Version 1.2 has numerous enhancements and fixes including the ability to have the reference number in the message body rather than the subject line. MailFiler uses a unique US Patented system of adding reference identifiers to all your emails. MailFiler will organize and structure your inbox, give you message history, handle bulk, junk and personal mail, give you a 'To Do list'. MailFiler remembers filing locations according to the message reference and by senders and allows for rapid and accurate filing of email messages. Using the unique references MailFiler can instantly locate filed messages and shows you the complete message thread. Extremely useful for anyone dealing with more than 20 mails a day, dealing with customers or projects where you want a reference number. Also great for structuring your inbox into sections such as New & Unfiled mail, bulk mail (subscriptions), Meetings, Personal mail, 'To Do' items and groups of messages relating to current email conversations. Saves you time and gives you a very well orgainzed email filing system."
