GIMP is one of the best alternatives for Adobe Photoshop and it has come a long way in becoming what it is now with powerful features and capabilities. If you are new to GIMP, you may probably be wondering how to enable single-window mode. By default settings, GIMP launches in multi-window mode split into 3 sections: the working zone, toolbox, and layers, and these are placed in middle, left, and right respectively.
Although this layout may appeal to few, others will feel it cluttered, therefore may want to switch to single-window mode. Fortunately this is possible and very easy – in fact some might have figured it themselves in first attempt, while the rest would have turned to Google and hence here. In the main window, choose Windows > Single-Window Mode and you are done!
All the toolboxes get merged into a single-window. You can anytime toggle between single-window and split windows by doing the same thing.
If you are yet to try out GIMP, you can anytime download and use it for 100% free.
