Make navigation panel expandable

[strump]

The problem:

While planing a route with OrganicMaps there's a lot of information and configurable parameters: type of route, intermediate points, elevation profile, etc. But lower panel shows only time, distance, and elevation graph.

Describe the ideal solution Bottom navigation panel should display some basic route info and be axpandable. When user drags the panel it shows all the details and allows more actions: change route type, save, share, select alternative path (if there is one), reverse, reorder intermediate points, etc.

Samples: See how it's implemented in mapy.cz:

1	2	3

Context: Changing routing UI could break users practices but would allow expanding functionality.

Moving route type selector from top to bottom will allow one-hand control.

So in short, when the bottom sheet is opened and is at it's minimal size , instead of just the time and distance, configurable parameters that you mentioned should be also visible when user slides the bottom sheet? I think I could add the setOnTouchListener() so whenever user drags the bottom sheet in the upward direction, the data within it dynamically changes showing all the remaining info.
