Have you posted these in our forums? That's really the best place to make sure it doesn't get lost. And it also helps give us an idea of how many people are affected.
We are doing our best to make things easy but, it is a brand new application with no shared components whatsoever with MB2. There are a lot of undocumented, magic features that work in MB2 just by dropping certain files in certain locations. I want to move away from that sort of thing and get to a point where every feature is configurable through the web interface. That way everybody knows about it and everybody has a chance to use it. So it's a difficult balance between moving forward vs supporting every last MB2 convention. We support quite a few MB2 features but at some point we have to move forward. Look at how long everyone has had to wait for MBT (and are still waiting).
