Prime documentation

As far as I am aware Prime does not come with a complete documentation and reference. We get the six small pdf's and the help which does not seem to be that comprehensive and is not that comfortable to use, too.

I know that the last documentation (which deserved that name) we got with Mathcad was that from version 11. Over 500 pages and I still use it, both the printed and the pdf version. Later, we were fobbed off with a stripped-down version, the "Mathcad Users Guide" - still about 170 pages and in the last versions in pdf format only.

Are there any plans by PTC to provide a comprehensive documentation and a complete reference again? At least in pdf format. Would be much appreciated!
