SUMMARY Version 21.07.70 on Windows, installed from https://binary-factory.kde.org/job/Okular_Nightly_win64/ By default there are 4 values for "Default zoom": 1. 100% 2. Fit Width 3. Fit Page 4. Auto Fit Would like to have certain custom level, like 70%, or previous value.
I think a good value would be "Half Page Height", so in widescreen monitors I see half of the height even if width is less than 100. So then with "Page Down" key I see each page in 2 keystrokes.
