Single-window GIMP with GIMPBox

GIMP from SVN (2.7.x) comes with a built-in single-window mode (can be disabled) but I find it unstable sometimes so I prefer to use the stable GIMP 2.6.x, especially since there are so many goodies you can use to enhance it, like GIMP Painter and GIMP Paint Studio, G’MIC or the GIMP Plugin Registry package.…
