An incredible addon :D Rated 5 out of 5 stars

Thank you for your valuable work done with Screengrab. I didn't know about your project because I thought that Screengrab was EOL. Would be possible to add the http link of the webpage to the end of the file's name automatically? :)

This review is for a previous version of the add-on (0.96.4c). 

In Windows this fails to save with an error because ":" is invalid
character in Windows filename. A filename cannot contain any of the following characters:
\ / : * ? " < > |
