I love that the messages have color now. I missed that.
The extra space around list items is good. Can something be done with the Send Message page? The various selections are pretty crowded.
I am finding the collapsing menu annoying. Every time you want to do anything, you have to use the menus. It is constantly being used, so I have to keep opening it every time I do something. Also, it's so tall that I have to scroll to see the bottom half of it. That makes accessing it a two click process instead of one, unless it's on the bottom half, and then it's click, scroll, click. While it's an interesting concept to hide the menus, I think this implementation is actually counterproductive. If it was always visible, that would be different. But as it is, I have to scroll back to the top to see it any way, so making it smaller doesn't gain us anything.
