I have a request regarding how the "Zoom to Fit" zoom mode works. I find that it doesn't zoom in enough. There is still a large border of empty space around the photo once you've zoomed to this level. Personally I feel that it would make more sense to make this empty border smaller, so that the size of the photo is as big as possible. I know that it is helpful to have some empty space around the photo for certain tasks, like cropping, but the amount of empty space that is currently there seems excessive to me.
I know that modifying how this zoom mode works may mess up some people's workflow, so maybe instead of changing it, could you add another zoom mode called, for example, "Zoom to Fit (tight)" that zooms to fit, but with a much smaller empty border?
I have attached two screenshots. One shows how "Zoom to Fit" currently works, with a large empty border around the photo. For the other, I have manually zoomed into the highest whole-number zoom percentage that fits the photo into the window (21% in this case). The photo is quite a bit bigger this way, which I find very handy.
