First of all, amazing work, thanks for the opportunity to help to improve Penpot 
Zoom pace: I’m finding the zoom pace too big and it is impossible to reach a zoom value in between the actual values.
How it could be tunned:
0% - 40% → +1% jump
40% - 60% → +2% jump
60% - 80% → +3% jump
80% - 120% → +4% jump
From 120% forward, it could be a procedural incrementation +1 percentual unity like Fibonacci or similar

Key maps for zoom and pan:
These are alternatives to the key bindings currently set that could be added to the preferences menu:
- Pan by dragging with right click (Similar to Unreal Engine 5 Blueprints Editor),
- Zoom with Scroll wheel instead scrolling up/down
