Steps to reproduce the problem:
1. Turn on Chromebook
2. It updates
3. New shelf looks terrible

What is the expected behavior?
I was expecting to be able to change the flag again. Now I just have this goofy looking device that I don't want to use anymore.

What went wrong?
It updated and took away the flag to revert back to the old shelf, because the new shelf looks like crap.

Did this work before? N/A 

Chrome version: <Copy from: 'about:version'>  Channel: n/a
OS Version: 6.0 (Windows Vista, Windows Server 2008)
Flash Version: Shockwave Flash 28.0 r0

Give us the freaking shelf back! What the actual fuck, guys? Is it really that hard to give us customization features for our own devices?
