I zoom in/out a lot, during (offroad) biking, to see if I can take a next turn or I have to go back in case I miss a turn.
Zoom in/out is slow (specially with auto pause) and I have to get my hand off the bars to touch the screen.
I use the Shimano remote buttons to control my screens.
It would be great if I can switch between screens, a direction map (normal view) and a zoomed out direction map to get a quick overview.
Maybe I can use Di2 programming to zoom in/out. But that is still slow, and I already use it for other functions.
