Embedding into posts? 100% CSS sizing?

Hey. Nice plugin. I’m having a few issues though with the buttons appearing in both posts and the ‘similar posts’ suggestions.

Can i add the buttons to the themes post page? If so what do i add?

Also, i’d like the buttons to appear 100% width of post. Currently they are centred and out of whack.

Thanks.
