Why don't you make one?
The only bad/weird thing is that there are also people doing some work on this on the xda forums and it's a pity that we can't/don't work together...
We could do something better!

P.S: Some guys there were talking about how to add more ambiences. So you had to decompile the package. It was the first time hearing about decompiling, so I have one question... When you decompile a package, does this mean you can see the whole source code, the one that the developers had wrote from the first time? If yes, why some times we bother about open source programs if it is easy to see the source code?? Sorry for this silly question
