Well, it'll be based on the 13.0.1 libraries...so you can look for some (most) of those features to be ported over. And there will be more bug fixes and enhancements working towards better integration with the Eclipse environment and the new p2 provisioning stuff. We will be launching a beta at some point in the near future, so that will give you a taste.
I do still have the dockable command line tool window as a feature in our tracker, and it was targeted for version 3.4, but I can tell you that I'm pretty sure it's not making it in this release. It just keeps getting bumped for more essential things. Sorry

. We will see what we can do, though...second request noted
