Probably best to wait with this until #6260 is merged.

@crisbeto, @mmalerba no major refactors are underway right now are they? I feel like this is a very important regression, especially the mode changing aspect.

This one is a really painful regression, any chance of getting an expedited merge, even so we can start using it via material2-builds?

The fix for changing modes has been merged: #6260. The fix for drawer removal is ready but not merged yet: #7060
