I once tried it but uninstalled it for one main reason: there was no way to tell when I got new messages. I didn't want an audible notification, and vibrating wouldn't do the job, unfortunately. What I was hoping this app had was an easy way to simply look at the screen and know I had new messages in my Email accounts. Unless anything with this app has changed recently, two questions remain:
1. Is there a way to tell I have new messages by looking at the K9 Email icon and seeing it indicate this? The stock Email client, as bad as it is, at least has a green number in the corner pop up and indicate the number of new messages.
2. I have multiple Email accounts (work, personal, etc.). Is there a combined message box or something similar?
FWIW, I'm using an EVO.
