Kinda useful, mostly not. Without the ability to easily remive packages, you easily get overwhelmed with notifications. Removing items is a chore, and frequently causes problems in the app. Useful for EXTRA notifications about packages, but mostly annoying to use because of the inability to easily remive useless information. This coupd be a 4 or 5 star app except for this pointless frustration. Let people swipe to remove a package instead of forcing them to press four buttons.
