SAB have an option to enable Histroy and also notes can be written, verses can be highlighted, bookmarks can be set. But it is not as much beneficial as it could be.
These features, specially History, is recorded only for current session. whenever app is closed, history goes blank. Or even app is updated, all notes, bookmarks, highlighted verses, history, all becomes empty.
These are very much needed features for any user. So, it is requrested that these features must be for every time. Even when the app is updated, History, notes, bookmarks and highlighted verses should get synchronized with updated app.
Furthermore, there should be login system with fb id or whatsapp number or gmail id, so that if the user have multiple devices, then all these should get synchronized on every device.
