placement of widgets in user interface

[Fredxxx]

The placement of widgets could be improved:

1. When browser window size changes, eg. made smaller, the widgets, especially the "Data analysis visualization", so the data itself, gets very small, whereas other widgets, such as the colour bar stays relative big. (might connect to Roberts comment -> mobile use)
2. Rethink widget placement. In my opinion (although I have no expertise in Brillouin data, so this might be wrong), some important widgets are out of the screen. Eg. the "Result display selection", where the visualization quantity can be chosen is not on the screen when the data is on the screen. So when changing display quantities, it is hard to see the difference or dependency of these quantities. -> You might want to compress these widgets so the drop boxes for these widgets are closer to the data and can be changed while the data is still on the screen.
