Many people would like to know how to put GIMP into one single window mode. Here is a quick tip.
GIMP Window Layout
When you first open GIMP you will see a split window layout. It will be split up across your desktop.
Most people are more comfortable having GIMP all in one window frame. In order to get GIMP into one window go to “Windows” > “Single-Window Mode”.
Congratulations now you have GIMP in one single window. 🙂
