Works great, but beware when using Polylang

For websites in one language this is great. Though in the plugin settings there is a dropdown where you can choose if the editor of the duplicated page should be Classic or Gutenberg. Looks a bit of a redundant choice to me.
The only time when I had an issue with this plugin was with multilingual websites that use Polylang. Duplicating the homepage (for instance because you want to reuse parts of it) resulted in decoupling the translated versions in the Pages overview. The plugin duplicated the homepage but the translated version came along with the duplicated page, moving them from the actual homepage. That was of course not the intention.
