Permalink Icon Feature

It would be great to have an option to add a simple icon/button for a permalink that could copy the link to the clipboard. These seem more common these days as a way to allow people to grab and share the link directly (e.g. buzzfeednews.com and many others). Perhaps even integrated with wp.me shortening.

Not sure if you are planning to add any features, but I thought this could be useful. Thanks for a great plugin!
