There is an issue when you try to save a form/survey edit, and you leave more than 5 or 10 mins without interaction with the forms/survey builder, which drop an error 401, and backing all the changes to the begining. That makes a little hard to work on editing things.

Option 1 could be a checkbox to allow to the form/survey builder to autosave all the changes when you make it.

Option 2 could be to disable the limit of time to make editions on the forms/survey.
