This is a minor suggestion regarding how zooming works in the key editor. I often need to zoom in and at the same time scroll up or down the screen, then immediately zoom again to find the right zooming level, and so on. What I do: use two fingers to zoom, then release the fingers, then use one finger to scroll the screen up or down, release the one finger, use two fingers again to zoom… and so on.
Ideally, it would be better to do all what explained above always with two fingers, without ever releasing them. But when you use two fingers (after finding the zoom level you want) if you scroll up (moving the two “still” fingers up), the screen goes down. And “scrolling” down, the screen goes up. This is not intuitive, so I dont do this, and as mentioned above I release the two fingers, and then use only one to scroll up or down.
Probably this is how zooming works, and its not a big deal, but if it can be changed as explained it would be nice.
