When you right-click a file in the Library and choose 'Remove from Library', the dialog that appears has the buttons 'Delete' and 'Cancel'. Surely the 'Delete' button in this case should say 'Remove' as I am specifically not deleting the file, just removing from the library.
It does say it is deleting from the library. Remove and Delete are the same thing. They should be consistent though in which term they use to indicate removing/deleting. If they say "Delete from Library" then the button should say "Delete". But if they say "Remove from Library" then the button should say "Remove", for consistency, which is important in a software package. TechSmith QC should have caught this.
