Thanks for suggesting Widget Options as a replacement. I'm the plugin creator and I've actually created a migration tool to move Display Widgets' saved preferences to Widget Options. It's my way of saying thanks to those who are choosing my plugin. The migration tool is available for free on github: https://github.com/phpbits/widget-options-migrator and has full details; and instructions here: https://widget-options.com/easily-migrate-display-widgets/ .

Cheers!
