Keep scroll position when swiping between days

[ltguillaume]

I think it would be a good idea to lock the vertical scroll position when swiping between the daily details panes: this way it would be easier to compare e.g. precipitation totals between the days.

Currently, when swiping to the previous/next day, the scroll position is saved individually for each pane.

Alternatively, by tapping on the tab, you could make the scroll position reset to the top (both on a different day, or on the current day).

I think this would greatly improve usability.
