I’m inverting colors with the following way, but it has no effect on epub and possibly other non pdf files.
The point of inverting is to reduce eye strain especially on long epub books. (>500 pages on a PC)
MainWindowBackground = #000000 EscToExit = true ReuseInstance = false UseSysColors = false RestoreSession = true TabWidth = 300 FixedPageUI [ TextColor = #ffffff BackgroundColor = #000000 SelectionColor = #f5fc0c WindowMargin = 2 4 2 4 PageSpacing = 4 4 GradientColors = #000000 ]
It would be better to have a simple ui checkbox to do this that works on every filetype.
