Yes technically, but perception is different. People publish the post by saving and its clear that they have to do this. The attachment is included then.
Its not logical that an uploaded file has to be confirmed again after succesfull upload. The user sees the file in the folder with all the other files and there is no visual difference between old (confirmed) and new unconfirmed files. I've seen it now by different users that this is a real problem.
Do you think we can make the little changes as suggested very quickly. Its only a new lang string and a new placement for existing buttons. No functional changes are required.
