Well maybe I'm not describing it correctly and it's been a little while so I'm going from memory. I know that when I tried to use K-9 for my comcast account and I had, let's say, 20 e-mails in my inbox. When I would go to the inbox, I would have a list of the 20 e-mails and when I touch the first one, read it, then delete it, it automatically opens the next e-mail for reading. I think I could back out to the list after reading a message, but if I delete a message while reading it, it will pull the next message up for reading. I didn't like that.
With the stock app, I can't set up an icon on my home screen for each account, but I can put my stock messaging icon there and when I click on it, I have 3 different icons for each of my e-mail accounts. Coming from my BB Storm, I had my e-mail set up that way on that device and I like it that way...
