Most of my writing is in Urdu, for which I have to write in the right-to-left direction, but there is no option to switch between RTL and LTR.
Hey @abusaadrashdy, 
We’re fully aware of how important RTL support is, especially for Urdu, Arabic, Hebrew, and other languages.
This feature is already in our roadmap for the Android app/iOS app, but unfortunately I can’t give you an exact timeline right now. As soon as we have more concrete dates, I’ll update this thread (and all similar ones).
Thank you for the request and for your patience!
