UI Enhancement: Allow zoom/scroll of the minimap during biefing

The fullscreen map already allows moving the map area with clicking/dragging the mouse and also zoom in/out with the scrollwheel.
Would it be a good idea, to also have the same functions on the minimap during briefing? I am putting this up for discussion, since I don't know, how much work this is to implement and if people actually would benefit from this.

Detailed request:
Clicking and holding in the minimap-window moves what area is displayed on the minimap. This allows to look at other things on the map while keeping the main view unaffected.
When hovering the mouse over the minimap, using the scrollwheel zooms the minimap in/out. This provides a quicker way to zoom than using the existing magnifier buttons.
