You can scroll also sideways because the magic mouse has no wheel.
Yes I know, I have a magic mouse too. You can also make an horizontal scroll with your trackpad if you have a laptop.
If I move my finger just a little bit sideways, the display switches to pane 2 and a have to use cursor key to switch it back to pane 1.
It's the expected behaviour, it's supposed to be an improvement... Why do you switch back with the cursor key? It doesn't work with a swipe back?
In version 4.18.2 and below this movement has no effect
It was supposed to be an improvement, personally I like it.
The program reacts extremely sensitive.
Horizontal scroll is a very special gesture. The program reacts as soon as it detects it.
