السلام عليكم

I think that it would be extremely beneficial to have a feature that allows you to change the background to a different colour. Say, Cream. Alhamdullilah, when I am reflecting and reading (tafsir and word-by-word), the white background (especially in dark environments) hurts my eyes after prolonged periods of staring. Cream colour would be extremely helpful as it is much more relaxing on the eyes.
