This should actually be categorized as a bug, not a feature request. Reason: content is CUT OFF on the left of my PDF slides and I have an impossible time to display it to my students during class time.

On the Windows app, if you Ctrl+middle mouse scroll, the zoom will instantaneously go down to 38%, then jump back to 67%. It should be smoother and stay at the zoom you set it at.

Same app, if you use the pinch gesture on the touch screen, the zoom behaves nice and smooth. I can zoom it in 1% increments, and at the same time move the content left or right to center it as I please. But when I release, the content snaps back to the left, and to 67% zoom.

Because the sidebar is in the way, it obscures the leftmost edge of the content.

BTW, the side navigation bar should be hide-able somehow, like a lot of apps do with a sandwich menu or some similar standard indicator...or a way to "size" the sidebar to make it narrower or wider.
