Screen real estate

[dkp]

I have a very big screen, so I can see the brain and several region panels at the same time.
I'm wondering if we could save some vertical space though to improve what can be seen without scrolling:
I think there are several places where you could layout components horizontally:

1. The name of the uploaded csv could be to the right of the Upload CSV button.
2. The fill color filter could be more like the slice selector slider (i.e. smaller and to the right of its label.
   3): In the selected region panel, it could be "Selected region: HG_L" instead of splitting that on two lines.
3. In the selected region panel, View and Slice could be on the same line, i.e., "axial: 6mm"
