Indeed is not a code hack of any kind. It is just a modification of the track files to make them as if they where recorded on a server with external views enabled.
I don't think we want to release this one to the public (at least for the time being), the main reason being, while under control, it can be disabled when/if we decide to do some missions where we do not want people to be able to have the externals until the mission is over.
With that said,
I can't understand why some people prefer to complain instead of thanking the hard work of others. We could have as easily kept it for ATAG members only instead of allowing others to use it.
As for the question about other things in progress. There are none that I know of but I'm open to new ideas
