Issue with zoom while navigating viewer window

As you can see in the standalone Viewer Appearance settings, there is only a place to set "Minimum window width," but I need to set a Maximum width. Here's why:

I like the "Auto-size" checked because, when "Auto-size" is checked, pictures open at their original size, and zooming an image with the mouse scroll automatically enlarges the borders. I use my left and right arrows to navigate through pictures. In some cases, the pictures have a very large size, and when I open them on my 38-inch widescreen, they fill the screen, so I zoom out a bit. But when I right-arrow-click to navigate to the next picture, it again fills the screen.

Turning off "Auto-size" prevents this, but when this is checked, the borders do not resize together with the picture when zoomed, which I need.

Adding a "Maximum width" setting would solve this since I can set it to not fill the entire 38-inch monitor unless I click full-screen.

If the pictures are similar sizes, turning off Preferences / Viewer / Behavior / Reset zoom level for each picture to may be what you're looking for.

(As an aside, the minimum width option is there to stop small images making the viewer so narrow that it truncates the toolbar at the top.)

This is an improvement because navigating doesn't zoom in again. Turning this off, however, creates a new problem. When I open a picture with dimensions larger than my monitor, I have to zoom out three times to see the entire image. This is what "Reset Zoom Level to Fit to Page" prevented. It's important for me to have the best of both worlds.

I want the zoom level to "fit-to-page," so that pictures never open so zoomed, forcing me to zoom out - AND, that when I navigate, the zoom I am currently on stays the same.
