I'm requesting the ability to have images the user switch to always be under "Zoom to fill screen" as long as the user holds the shortcut key for that function. That way users can use this zoom function only when needed, without having the need to toggle the setting for it every time.
Sorry, meant "Zoom to adjust". I want to maintain this effect when going to the next image by holding the shortcut.
I guess that in order for this to work, the one frame Bug 497118 would have to be fixed. This feature is most useful for comparing similar photos, or screenshots of neighbour frames.
