The collections feature it a great idea but it just doesn't work. I've added verses to collections and they don't save. I've added verses to collections that saved and then just randomly disappeared. I've deleted whole collections numerous times but they still appear in my collections. I've invited a friend so we can do a collection together and it didn't work. So basically the feature doesn't function at all.
I really love the idea of collections though. Please fix it.
Also could you make it possible to swipe and delete a collection, or maybe put an edit button in. At the moment the only way to delete a collection is to add a verse (tricky at the moment) and then go into the collection and delete it.
