Because of my job, school, personal life and ISP restrictions, I have four e-mail addresses. Some of you probably have more! I like how Apple created the unified e-mail box ("All Inboxes") aspect of the Mail app in iOS 4.0. However, it gets a bit confusing trying to figure out which e-mail is for what purpose. Color Mail Labels to the rescue!
Color Mail Labels ($0.99 USD):
[Cydia Description]: Ever wonder if there was a way to organize your iPhone/iPod e-mail accounts the same way you can on Gmail using color labels? Well now you can. Color Mail Labels is a simple tweak that will allow you to do just that. Use the Mail Labels app [icon] that is added to your homescreen. It allows you to configure which mail accounts get colored.
Now, with each mail identified with a color, I can easily tell which e-mail is for which account:
If you back up/out of your All Inboxes, you'll see each account is coded a different color:
The set up is very simple. Buying and installing the tweak puts an icon on your homescreen. When you activate it, you get options to select an e-mail account you have loaded on your iPad (this works with both IMAP and POP accounts). After you select the account you wish to modify, you get a color-picker screen. Use HSV, RGB or Hex codes to select - or just touch within the color box (the bottom bar controls saturation).
There are many options to display the colors: big rectangles, small squares, etc. As you can see from the first picture, I chose "Colored date block" (because the color still shows when the e-mail is highlighted).
I recommend this tweak to anyone with more than one e-mail account. It aids tremendously in organization, is highly customizable and is darn cheap! It's one of my favorites, although, as always, YMMV.
