I want to be able to click on the zoom% number and type in the exact percentage of zoom I want. If I “tap Z to toggle” it bounces between a fit-to-screen size, and 75%. Currently the only way I can find to zoom 100% is to carefully, methodically, surgically drag the zoom slider to 100%.
Additional zoom problem: once you are zoomed in on a picture, the image bounces wildly around the screen depending on where you move your mouse. Ideally when zoomed in, the image would remain still until you click+drag to where you are interested in seeing.
