One thing that hasn't changed in a while, is this.

The loading screen (and by the way I'm really sorry if it was meant to be temporary for until the release of FlightGear 3.6). I definitely saw something that could be improved on.
Even with my limited skills and knowledges on designing, with 2 and a half minutes of photoshopping I was able to create something like this.

Now, I know it still looks pretty stupid, but I created it just for demonstrative purposes. I know there are people out there in this community who are much better than me at designing stuff.
- I don't know. Maybe there's a reason why it's kept like this. Or it was meant to be temporary.
EDIT: I do love the pictures in the splash, I just feel that it should be bigger.
