I have added a lot of shortcuts to the app's library but there are many that I no longer use, how do I get rid of these shortcuts?
There are tons of shortcuts available for the Shortcuts app, with new ones being created every day, and if you like to check them out then you have to add them to your library. This invariably leads to a cluttered library, so you'll want to get rid of the ones you don't use. Deleting shortcuts from the app's library is similar to deleting an app from your iPhone or iPad's Home Screen - just long press on it until all the shortcuts start to "wobble," then you just tap any shortcut that you want to remove so a blue check appears on it. Once you have selected all the ones you want to get rid of just tap the trash can in the top right. It will ask you to confirm that you want to delete them, do so and the shortcuts will disappear from your library. You can, of course, add them again from the gallery if you wish.
