There isn't a list right now and to be honest I'm not sure that there will ever be one. My personal opinion is that we should expose as many of the customization capabilities through the admin console as we can and then the rest of the properties through JavaDoc. Are there specific things that you're looking to do that we can help out with here?
I wasn't looking for anything particular this time, but I thought I might get some ideas if I saw what was available.
Thanks for the reply.
