Questions about the "Changed Files" tool window

I recently upgraded to IntelliJ IDEA 14 (from 13.1), and I don't like the UI redesign of the "Changed Files" tool window. Is there a way to revert this back to the way it looked in v13?

Specifically, what I don't like is:

1. Since the tool window is now combined with the "Project" tool window, I can't have both open at the same time, and switching between them is more of a hassle because now it takes 2-3 clicks: clicking to show the tool window, then clicking the dropdown arrow, then clicking on the other type (i.e. Changed Files or Project).
2. The tool window's mini-toolbar has disappeared, so there is no longer an "Expand all" option. This button was really handy to see a quick list of all the files I've changed locally.
