As you can see, I changed lobby design myself. I replaced "blue-gradient theme" with "black & gray" (in the lobby)
I'm still not sure if it's good, some people already say they like it, some people already complained. If you think that you could improve it, the please:
1. take a screenshot of the lobby
2. load it to your favourite graphics editor
3. try to find some better background color, and better colors for gradients in menu titles.
4. you can do any oher changes in layout / coloring
5. if I like it, I will use it
