Currently when you disapprove a post and select it for inline-moderation you still get the option to disapprove the already disapproved post. You also have always the option of approving already approved posts. My suggestion is to remove all options that are not needed. - If a post is already disapproved, remove the disapprove post option from the inline-moderation - If a post is already approved, remove the approve post option from the inline-moderation - If a post is not deleted, remove the undelete post option from the inline-moderation ... and so on. Please get rid of all unnecessary options and display only the needed ones.
