One extremist person's view that Gimp should not support MDI (mulitple document interface) persisted for 15 years, then they relented and added MDI, after the person who was against MDI violently criticized Gimpshop (I think the homepage for gimpshop has been hijacked, don't use it). That person got others to start a lengthy and patronizing "UI ideas process" that was a smokescreen for going back on the MDI idea - when in reality the problem was the code to allow the UIs to dock properly - and to this day when I use GIMP the way they dock and tab the UIs goes against any learning model in my mind, and takes me forever to realize that what I am trying to find it hidden away somewhere.
There's no good model to the UI (and the problem isn't even a difficult one) because it's trying to straddle one person's personal ideas with a common and clear mental model of how certain actions should be grouped.
