send and recieve

As a kid I used to play with walkie-talkies. These radios used to have a talk button. When you wanted to talk, you needed to press this button. The point: you could either listen or talk, but not both at the same time. I realize that mailxel helps me to apply this practice to mails: rather than to get distracted by incoming mails, the separation of sending (replying) and recieving (downloading mails at specific points in time) helps me to keep focus when working through my inbox.
