Zoom V3 and V4
Map zoom system is not really pleasant to use, mainly on laptop Windows.
Why don't use + or - functions or zoom in zoom out with mouse ?
A static tool on the right side would be easier to use thna the system of arrow on V3 and V4 versions.
2 boxes to click on (or touch on ) one with + and one with - would be better (for me !).
Right you are, agree Jef
