Q: Is it possible to protect videos as well?

A: It is not possible to protect videos that already exist in your device.  3rd party applications do not have access to users’ video files. 

Q: Is multiple import possible?

A: Yes, I’ve figured out a way to support multiple import from your existing photos.  You will still have to click on each photo, but you’ll be able to do it much quicker.  This change is included in the next update, which was uploaded on September 15th.
