[Plugin: Share and Follow] Feature request: floating buttons

It would be great if you could add floating buttons just as on Mashable.

Similar to what you already have for the Follow buttons, except that these floating buttons would start lined up with the top of the post (i.e. would adjust according to the theme). Then as the user scrolled down, the buttons would scroll until hitting near the top, at which point they would stay fixed in the same screen position.

I’m primarily interested in having the interactive buttons there first.
But I can see other people wanting to have all the other share buttons in there as well.
