Hi Nels,
no need for that.
It's exactly the kind of feedback I needed and matches my own limited test driving.
I will release that as a version later this week.
However it's a good call to streamline the experience of selectively testing alpha or beta combined with only few unreleased features in Framework_6_0 or feature branches.
