On widescreen monitors, sometimes there are too many words per line to read if you have the Viewer maximised. Changing the page layout/margins based on pixels can limit the words per line in a correct manner only if the window is not resized and the font size stays the same.
For a more ergonomic, faster and less tiring reading experience, I have following suggestions:
- Adjustable limit of characters/words per line. About 10 words could be standard.
- Dark background mode: In window mode, the entire background could be darkened or blurred to allow distraction free reading.
