Until somewhere around September 2020, on MacOS client it was possible to pinch zoom to any point in UI using the trackpad (similar to pinch zoom in Safari or Chrome). Now this feature is gone. A number of of users found it great for zooming in on album arts, profile pictures or other pictures in general.
This is not the same as the available zoom that just scales the whole UI (View > Zoom In). I am only refering to pinch zoom done with a trackpad.
