Great work Peter but i think you went too far the other way now, it definitely works better but it is too severe the other way.
Heres a good test.
Choose a 4 minute song
Zoom in on it fully.
Create an open finger peace sign with your average sized fingers.
Now do the zoom out gesture to show the full 4 minute song.
The fingers should fully close at the same time as the song should be fully zoomed out.
At the moment you only move your fingers half way and you are already zoomed out fully , this is too severe and does not make full use of the screen space plus it is too sensitive when you want more precise zoom point.
So if you reduce this setting back the other way just a little bit you will find that sweet spot.
Before you had to do the peace gesture 3 to four times now its a half of one gesture, if you could make it a one gesture to go from one extreeme to the other that should be perfect.
