Rated 5 out of 5 stars
Great add-on for users that want to copy plain text instead of formatted text. The preferences menu provides useful formatting options. Additionally, it allows you to use the extension by replacing the default copy action or by adding a new hotkey-combo and context menu item.
One suggestion for improvement: Add a preference that allows users which have replaced the default copy action to copy text with formatting using ctrl-shift-c. That way, users which have replaced the default copy action can still occasionally copy text with formatting without having to change preferences.
