Just downloaded the latest version. Looking good.

I have a couple suggestions related to survey notification to the author when a survey is completed based on some feedback I got from my users:

1. It would be great if there was an option to turn off notifications so the survey author didn't get an email every time a survey is completed.

2. When a survey is marked as anonymous, the notification email probably shouldn't have the name of the submitter in the email. It's not truely anonymous since you just have to look at the survey response time and the email time to know who completed the survey.
