I've launched a new program available for heavy email users. It has two basic funtions that can save heavy users a lot of time:
Fast Email - Add an address for a person that you commonly email and you will get one click access to their email address from the BlackBerry message list.
Fast Forward - Add a list of address(es) for people or groups that you commonly forward email to. So could be your home or work email or joke list, whatever.
Commercial use but 3 day trial available from Handango:
FastMail by Adrian Logan Consulting - Handango BlackBerry Software
Currently can be bundled with another app I have created that alerts you when you have missed a phone call since the BlackBerry has no built in repeating audible/vibrate notification. (20% off each when bundled)
Let me know anyone has some suggestions for new features but I would like to point out that Fast Email contacts can only have 1 email address and when adding contacts from the address book that have multiple email addresses you will be asked to specify which email address to use twice (the first time is by the BlackBerry OS but this data is lost so my program needs to ask you again).
