The Quest Scroll can not be moved or minimized on the main map screen.
This can be a problem is your destination is located in the upper right corner of the map, thus making it difficult to see.
Possible solutions:
Being able to drag the Quest Scroll to another part of the map.
Being able to “roll up” the Quest Scroll.
Placing the Quest Scroll on the Icon Bar in the upper right corner. Press Icon and the scroll will appear / or roll up / unroll
