I also use gimp for simple "cleanup" tasks and brightness/contrast. I wonder, what is the alternative you are using now, and if it's free like gimp?
ksnapshot, krita/inkscape, gwenview, darkroom, rawtherapee

darkroom is called darktable :)
Libre office added ribbons etc as an option. It is not forced on anybody.
