Popular Mac, Linux and Windows image editing app GIMP has been updated to version 2.8. This latest version overhauls the UI to offer a new single window mode that lets users edit images, choose tools and set up docks all within one window. Earlier versions of GIMP had multiple windows for tool sets and images, which was confusing for some users accustomed to a single window work environment. If you like the multiple window paradigm, don't worry as GIMP lets you choose between multiple or single window mode.
