Okay, lots and lots of great feedback here.
The oddities like a missing space below the tree mail watcher, and the bullets outside their boxes, are things I'll be addressing one by one.
The floating bar... here's the issue: it's something that I was having a lot of trouble with. It was causing incompatibilities with several devices, which is why I made it stop floating and moved everything to the left. Now, I know a lot of people have become accustomed to it (me, too!) so I'm exploring options.
