FEATURE REQUEST: Option to remove ARABIC tashkeel

As others may have also experienced, having the tashkeel (diacritics) on the arabic text can immensely add known words, even though those words you have already learnt in their non-tashkeel form. This gets annoying as it feels as you are cheating yourself.

Just having that option, when being in the lesson editor to remove such tashkeel will be very beneficial. Hope you can add the feature.
