If you take advantage of the ability to take screenshots on your iOS device every once in a while, then you might enjoy checking out a new free jailbreak tweak called Screenshot Extender
by iOS developer honami to give yourself a few additional screenshot features.
Once installed, the tweak will add a new preferences pane to the Settings application where you can start getting your hands dirty with some new features. You can customize most of them to your liking:
From here, you can do such things as enable or disable the tweak on demand, configure your screenshot flash color with a hex color value of your choice (#FFFFFF [white] is the default), and configure a confirmation alert that lets you know when a screenshot has been saved to your Camera Roll.
If you're not familiar with hex color codes, you can visit this Web page
to find out some hex color codes for popular colors.
From the confirmation alert settings, you will be able to enable or disable a confirmation alert whenever you take a screenshot. Your alert can be in the form of an alert pop-up, or a banner notification, and you can configure the text that appears, as well as the application icon that appears:
For the most part, this tweak doesn't offer any useful features apart from the ability to change your screenshot flash color. The notification alerts can sometimes get in the way of your screenshots if you're taking multiple screenshots at once, so it's hard to recommend that feature unless you're just a casual screenshot taker.
If you would like to give Screenshot Extender a try, it's available for free right now in Cydia's BigBoss repository.
