[Option] Make text fits the screen

[Iam-Muslim]

Alslam alaikom my brother ,

• Defining new color for text is not saved.

• The text in a surah is not the same , some ayahs are long and some are not. if i make a font of 70 , margin 15 it can fit a short ayah but a long ayah not fit in the screen . maybe you can add a option to fit the screen ( or fits a desired area which i choose ) automatically for all ayahs to make sure the text uses all the desired area to be read by eye well ( if i made a font for all the surah , some ayahs will have small area and long ayahs will take the same place and be hard to read by eye for short ones )

I've split this into two as they are separate issues. See #17
