Man! This is an awesome plugin! I LOVE how customizable it is!
But do you know what would bring it to a whole new level? Adding a
"Display total shares" !!!!!
Someone has already created a new plugin called "Share Pulse" that has successfully integrated the combined Share API data of FaceBook, Twitter & Digg. Unfortunately it isn't at all as customizable as yours, takes up way too much real estate, has too many share icons (too repetitive) and isn't even multi widgeted to allow for different timeframes.
You already have the perfect foundation for adding probably what will be one of it's most appealing features. People want to know what posts are being shared most in an organized way. The future is here and it's all about sharing! Let me know what you think!
