External Hardware Support
Much like Photoshop, GIMP is compatible with a wide variety of graphic manipulation external hardware right out of the box. So if you are most comfortable with a specific mouse with special gestures, or if you have a pen display controller that you’re used to using, you can customize it to speed up your work flow when you use GIMP.
Even if you are a traditionalist, and use a two-button mouse and a standard keyboard, you can customize the hotkeys and shortcuts in GIMP. In doing so, you make your workflow much more efficient. Since GIMP is so customizable, once you have used it a couple of times, you begin to get a better sense of what you do and don’t use, and can adjust your interface accordingly.
With GIMP’s external hardware support, you can quickly undo mistakes with a single mouse click, or set up a hotkey to create a new document with a single click or combination of keys. Many users, especially ones with an art background, prefer a “pen and tablet” controller for graphic design work, like products put out by brands like Wacom. These controllers are fully compatible with GIMP and allow users to interact with their computer as if they were drawing with a pen (or in this case, stylus) rather than re-training themselves to draw with just a mouse.
