Currently, for an auto-merge enabled PR, the review area looks like this:

Sometimes I want to approve a PR, but provide comments that the author may optionally want to address. In these cases, I disable auto merge before approving so that the author has a chance to look at my comments. It'd be helpful if the auto-merge state was shown in the approval area (or, even fancier, have the checkbox to enable/disable it) so I don't have to go back to the main issue to find it.
