Right now there are design pictures like https://app.zeplin.io/project/5e69f3010a273719afc8ae48/screen/5ecb87ef6b27e649abd82d6d which have a small mark on the top of the "bottom sheet" which indicates that it could be moved. Currently, we have left out this mark and the areas are not movable but can be completely hidden by clicking on the full screen button on map (which does not exist in design pictures).
Behaviour of "bottom sheets" on mobile is clarified.
Bottom sheet could be freely adjustable like in HSL app. However, if that is technically challenging to implement, a maximize/restore button like now is an acceptable solution.
