I've been using vue since version 4 and it has always had problems.  The ethics of the company has forced me at version 6 to stop being fooled.  There have been many broken promises about their feature list that have never worked well.  The next version sometimes fixed the problems and other times it did not.  I've learned how to spot their bull early on and this release seems to have the most beef and horn in it.  Hd Trees?  Nice buzz phrase, but I'll pass.
