What you guys should really focus on, I feel, is this part, where most of the settings and UI configuration is intuitive, where it suits majority of the people if not all.
I guess if there'd be a universal definition of an intuitive UI, gnome and KDE would look the same and Windows would follow suit. The reality is that there's a couple of different philosophies and camps each with their own notion of what is intuitive.
There's also force of habit - having used the FG settings for so long, I find myself right mouse-clicking in Orbiter to change from control to view mode - which doesn't work of course. But that's not Orbiter's fault. I had a hard transition period to gnome 3 at some point, now I wouldn't want to miss it for the world.
Anyway, it's OpenSource, the majority of configs are exposed on the xml-settings - if someone comes with an idea how to set defaults and that idea sweeps everyone off their feet, I'm sure it gets implemented. But my suspicion is 'the UI is not intuitive' really means 'I personally am used to a different UI' and really has only a very tenuous connection to what other users think.
