I'm not disturbed, by the silence, nor surprised.
It comes with the territory these days, I'm afraind, not just with Apple, but with so many companies, particularly those you have to go through a virtual minefield with, in order to contact a "real," person.
However, hopefully, someone is actually scanning these boards and the message will be passed on to someone among the powers that be, and D.J. will quietly be re-introduced, it shouldn't be that difficult 😉
In the meantime, I was so hacked off at losing one of my favourite features, I un-installed "11," and re-installed "10.7," and was all excited about getting D.J. back only to find that I couldn't open "10.7" as the Library had already been attached to "11.", so I had to re-install it.
If there were a way round that, I'd switch back right now and hold onto "10.7." till Apple have sorted it out 😠
