As the others said, there is one, but it isn't publicly available and probably never will be. The closest you have to knowing what is on it is by reading any responses Khaled makes on the forum. He will occasionally mention things that are on the list.
The reason he likely won't make it public is because as soon as he does, a LOT of people are going to start bothering him about getting things on the list done right away instead of letting him work at his own pace. I know from experience that you rarely want to tell people what you plan to add in a future release or when that release will be. It's counterproductive.
