Have to agree with a lot of the comment:
The good: left nav hiding option, separate scrolling, cleaner look
The bad: contrast in menu's (left + GA account picker) is too low hurting usability, need a compact option like gmail (remove all the useless white space)
The ugly: mixing G+ and Analytics account (righthand picker becomes unmanageable once you have 20+ G+, GA account, properties and/or sites. Only option is to fall back to the home option, which is a pity.
