A theme for monochrome screens (e-readers)

Please add a highlighting schema that is usable for monochrome screens. When using the Lingq app on my monochrome Android e-reader, it is impossible to distinguish between new and known words since both have similar light-grey backgrounds. Switching to “Underlined” does not help either. It would be helpful to draw a “box around” for Lingqs and use background highlights for known words.
I know there are workarounds for the browser version, but having the schema in the Android app would be great.


Thanks, we’ll see what we can do.
