Last night I came across a great app which I can quickly see becoming one of my favorites. Flag Your Emails lets you easily - well - flag your emails so you can keep track of important ones. I was constantly leaving items unread, only to forget and "Mark Prior Opened" a few minutes later. I'd forget what email I wanted to get back to, and that was that. Now with Flag Your Emails, you can toggle a flag on messages and the app will throw a red exclaimation mark next to the message (the same mark seen on urgent or high priority message). Then you just have to scroll through your messages and can easily see the ones marked. The app adds a simple "Toggle Flag" item to your menu and thats all there is to it. You can grab Flag Your Emails for only $0.99 in the CrackBerry App Store through Sunday.
