I am so glad you raised this issue clout. How many other "features" of 2.0 have been pitched to the community as important (which they are) but yet we've not been provided the necessary information on how to use?
It essentially renders these important features useless to the community. So much of the BitShares ecosystem can be viewed in this light. Even how to use stealth accounts from the cli was not documented very well. I have just gone through the exercise of setting up a stealth account and transferring funds into it as a test and to familiarize myself with the existing functionality. It is very cumbersome to use and IMO not very practical right now.
Stealth, multisig, changing UIA parameters are only 3 examples of features that have inadequate information on how to use, and limited to zero functionality in the GUI to access.
This highlights one of the largest shortcomings of the BitShares ecosystem from it's earliest days to the present, a lack of documentation and information. Mumble is a good way to get information at a 5000 or 10000 foot level about features and plans out into the community, but quite ineffective for practical, ground level information. Mumble is more about sales, marketing and policy when you get down to it, not about getting things accomplished. For that we need more detailed information.
