I'm always looking for new ways to speed up taking screenshots and the less mouse clicks the better in my opinion.
That's why Desktop Screenshot Whiz rates highly for me because it reduces screenshot taking to a simple press of the Print Screen key. Simply by hitting this key, the screen that you've currently got open is captured and opened in Desktop Screenshot Whiz which then offers you a range of editing options. This basically means you can select a certain region of the screen or take the whole screen. The program supports all of the major image formats and importantly, also allows you to apply text and some basic shaping effects such as adding triangles, squares and rectangles. You can improve the image quality with a few post processing effects such as filters. The program sits discreetly in the system tray in between captures which you can save to file, print immediately or save to the clipboard. The program wins lots of points for its ease of use, configuration and save options but the editing options are too limited to make it a great screenshot tool. Even basic tools such as a spray paint option or erasing tool are not available but if it's speed you're looking for, it's just the ticket.
A quick and easy screenshot tool that just needs more editing options to make it more useful and competitive compared to it's rivals.
