Yes, storing them under MyDocs is the best option. And maybe the format should be simple like csv or something, so that we can use our own translations apart from the ones that you will package. A lot more flexibility this way IMO.

Also some more feature requests (sorry ): 1.Can u add a way to select page or ayah number instead of just Surah?
2. Would it be possible to have multiple fonts as although the current font is legible, i don't like it much. Or will there be compatibility problems with the text?
