Please keep Office Mix if you cannot improve Stream

I really hope that Stream will be improved to match the needs of EDUCATORS who had such positive experiences with Mix.  Many of the concerns raised by Sean are the exact issues I face with the forced transition from Mix to Stream.  It is clear that Stream is NOT a replacement for Mix, especially for those of us who used Mix for educational purposes.  I hope the changes to Stream come quickly, but I fear that the focus is on an alternative product that does not match the needs of educators.  If you didn't intend for Stream to be a replacement for Mix, then why force all of our Mixes into Stream while not having the necessary tools available?  Please consider extending the availability of Mix while the Stream updates are being made.  I really don't want to learn another platform such as Adobe or Camtasia, but Stream is not suitable for my needs.
