When kate has an new file while closing the application it requests to save it. It would be nice to have the same behavior as on notepad++: It don't asks the user on close for save new file(s), they are just saved in the application directory on a temporary filename and restore them on start. This is very useful in case of interruption (reboot, crash, end of work, ...) This should be enabled by a setting like "Save unsaved file(s) on open".
Seems to be double created. *** This bug has been marked as a duplicate of bug 493729 ***
