User interface

GIMP has a unique interface that, in many ways, is not like PhotoShop. However, it does have a similar look and feel as the famous raster graphics application.
There are two modes for users to choose from: single-window mode and the separated view.
Single-window mode
The single-window mode puts all the tools and pieces into a single window. This allows the tools, open images or artwork to be kept together.
If multiple images or artwork are open in this mode, they will be thumbnails above the active image or artwork.
Separated view

In this view, the image or artwork, the toolbox, layers and the hardness items are in separate windows, floating over the desktop. They can be move independently from each other.
If there are more than one image or artwork open at the same time, they will appear full-size in separate windows, floating over the desktop.
Menus
The toolbox and layers and hardness items are not the only way users can edit images and create raster graphics.
GIMP has 10 menus with items for users to choose from. There is also a Help menu and, if you are a Mac user, a GIMP menu.
