Backup function allows you to save, load or delete settings configurations.
This is useful when you need to try some settings but you don't want to lose your current configuration.
Use save function to store the current extension settings in a json file. If the name you choose already exist in the list, the corresponding file will be overwritten.
Save function is asynchronous, so the page is not reloaded on the button pressing.
Settings configurations will be saved as json file, placed in "/settings" folder, inside the extension folder.
Use load function to backup load settings from a file.
Use delete function to remove selected configuration file. After this operation, deleted file can't be recovered.
