Hey maintainers attached is a patch for adding a functionality to the SettingDialog in the GUI of Octave. It adds two buttons to the bottom of the dialog namely "Discard" and "Save Changes". Discard : Will discard all the settings made this time and revert to the last configuration .
Save Changes: Will do the default , will save all the changes made.
Hoping for a favorable reply. -- Atul jangra Computer Science and Engineering Indian Institute of Technology ,Delhi
