If you need manager : put something (1 or "true" …) it's checked as a boolean.

«Also, is there a way to have the response list as the "home" page when someone access the survey? »

No

Thanks Denis!

I'm seeing a little bug when deleting submissions from the list; When I delete the submission, the page gets blurred while working on the deletion, and when the list appears again, the deleted submission is still there (even though it was successfully deleted).

Also, is it possible customize the list page, by adding links or buttons for example?

Please : report issue on gitlab.
I just check on 3.X and Firefox : no issue.

Same for feature request (i have to move to twig file : but take time …)

Else : you can add a description
