Gimp's single window mode was made the default years ago now, so that's not a great example anymore - there's scientific software that uses that paradigm that might work better, but most of that isn't OSS. Also, Libreoffice being slow and having bad font rendering seems pretty inline with Word nowadays...

Good to hear. I use GIMP pretty seldomly and that was always the first menu option I had to hunt down.
