CloseReview for QuickNote by Larashots
Rated 5 out of 5 stars
Just a head's up for the user named FoxTail: QuickNote has an option to "add the copied text's source"— http://i.imgur.com/Hh8iHv2.png
As for adding the date, for Windows users, pressing F5 adds the full date & time, (just as it does in Notepad). Since Quicknote opens after text is sent, it's really a non-issue to hit one button. :)
