AC came across a very cool tool, Brain Scott’s Cropper. I played with it a total of 2 seconds and was hooked! It easily and quickly takes screenshots.
And while I am on the subject of tools, on of my favs that I use A LOT is Sizer. It allows you to resize windows based on different resolutions, so for example you can check out what a web site looks like at 800×600 without changing your own personal display resolution. Very cool!
