Ramadan doesn't always start on the same day for everyone and within the same country people can begin on different days. It would be good to have some kind of feature that allows you to amend your start of Ramadan accordingly i.e. Saudi Arabia sighting/ global sighting, local sighting, etc. Or something that just lets you pick the day the months starts and take it from there. This would help align the last 10 days to be tracked properly too etc. in general as well this can affect the way ones other islamic months start
