Scrubby zoom

It would be great is Harmony had the ‘animated’ or ‘scrubby’ zoom like Illustrator and Photoshop. So when you hold down command + space moving the mouse left or right zooms you in or out.

indeed! Its ridiculous that this vintage artifact is still a part of the program with no option for changing to a “modern zoom” with dragging the mouse while holding a button.
These are the only current zoom options:

Either, roll the Mouse Wheel up or down…

Or, if you are using a Wacom Board, set your Pen to Pan/Scroll…

There is scrubby zoom. Hold down space and middle mouse button and move the mouse up/down.

Space + mouse wheel button held down, move mouse up and down.
