I could see where this would be very beneficial for a niche like mine. Frequently we may update our capture target with different exposure time or filters... and the ability to denote that in the post itself would be handy. As it is, it only shows on the first post.
It does need to be a node specific restriction though.
This could be helpful to add a radio button to posts (and maybe toggleable for in quick reply) for "Affiliate link disclaimers" so if a member includes a affiliate link, it can show the disclaimer at the start of the post.
