It would be great to be able to manually change the location to see prayer times in other cities. This would be especially useful when travelling and needing to know the prayer times in a city ahead of time.
I understand Pillars is all about simplicity and ease of use. So perhaps this could just be a feature that can be toggled on/off so nothing changes on the surface but if one needs multi City info they have the option to find it and not have to Google it on the side.
