The ability to move around in the canvas, especially with larger workflows is phenomenal! You can move up and down with the scroll wheel, left and right by holding shift, and zoom in and out with control.
The results window is a different story. While zooming in and out might not be useful, shift + scroll to quickly and accurately slide through the results window would be amazing. Often when setting up the next tool, developers will reference the results window, and navigating to the correct field can be cumbersome, especially when the amount of fields quickly increase.
Apologize if this is already an idea, but I didn't see anything when searching through the ideas.
