Function improve:why original one cant be deleted after moved to anther collection
1.when the item dragged out of the original collection to another, it is still in so there are two copies of it
2.when I deleted a collection unconsciously, does it mean I can't find it back if already synced?

2) There isn’t currently a way to restore a deleted collection, but do note that the items themselves are probably still in your library. If it’s not too many items, you can just recreate the collection manually. Otherwise, see https://zotero.org/support/zotero_data#restoring_your_zotero_library_from_a_backup
