If a user intends to delete the entry at index 5 but accidentally types delete e/6 instead of delete e/5, there is no chance for the user to correct his mistake and the program immediately deletes the wrong entry. This may cause significant inconvenience to the user when trying to track down his mistakes. Perhaps an error protection confirmation message similar to the one given for the purge command can be implemented.
