Improve mobile version

[FLomb]

The mobile version of the interface looks good. However, the sliders and the spore plots span almost the entire width of the mobile screen. As a result, scrolling up and down becomes a bit tricky, since it is hard not to accidentally zoom in on the spore plots, or modify the sliders, while moving the finger up and down.

A possible improvement could be to slightly reduce the width of the sliders and spore plots. Or perhaps there are better solutions for mobile that I'm not aware of.

On some screen sizes, it would be nice to allows the charts to "regroup" to make use of empty space below, as well as remain readable.
