The Input widget now has an Auto Save option which reduces the number of clicks for a user and improves the user experience.
This option is by default Disabled.
When the option remains Disabled, you have to manually click the Apply (formerly Save) button under the input fields to save your changes or the Cancel button to restore the default values.
When the option is Enabled, there are no buttons under the input fields, and the restoring of default values is possible through the options menu of the widget itself.
