I honestly do not get the "it looks ugly" comments.
I do not spend much time looking at the interface anyway. Click menu, click menu item, app opens, use app ... or ... open terminal, type what I want to happen, it happens, go outside to play with my dogs.
My only requirement is that it works. The easier to make it work the better.
But I guess that is why I write code and do not draw little pictures to make people happy.
PS. Yes I use ubuntu too. But I have not changed anything on the interface, still using it as it came out the box (or off the free CD they sent me).
