This is a terrific plugin you have released - the best and most flexible of the social plugins I've tested.
I noticed one issue, which I'm wondering if you can change/fix, or perhaps there is a setting I missed. Also one suggestion.
1. Twitter Button function: The Twitter button (not the retweet button) that is selectable in the Social Buttons menu uses the WordPress post ID#, instead of the permalinks. Can you change it to use the permalinks? I noticed the other buttons, like FB use permalinks. For users, it can be confusing, in terms of whether they are linking to the correct page (Twitter shortens now anyway).
2. Suggestion: This is a matter of taste, but you may want to implement it. I suggest a "no count" option for the Google +1 drop down (in the placement menu).
Thanks for the terrific plugin...
