Accidents happen, which is why Nifty has a Trash in your Workspace. When specific items are deleted, they will be stored for 30 days (and in some cases longer) within a "soft delete" before being removed from the Workspace entirely.

You can find the Trash via your dropdown menu.

From within your Trash, select the item you wish to review from the lefthand side. You'll see deleted items, who deleted them, and how many days until they are removed from the Workspace entirely.

You can click on items to select them and then the Recover button to bring these items out of the Trash and back into your Workspace.
