There is no save button (only a menue entry) and the tool will not warn you about unsaved changes! I consider this a must fix!
This defect is considered MUST-FIX for Florence Gold release
There is a big, shiny *Apply* button, that both saves and restarts lpd, so I am not adding a *Save* button. But I'll agree that it should warn you before you quit.
cleaner, with a warning.
