Anyway to unclick approve?

That's happenned to me a couple of times but not recently since I think Founder changed the layout a bit to make it harder to do that (I think the Pubish button is smaller than b/f making it harder to press by mistake) - but no, once you approve it there's no turning back - perhaps some kinda 2-step publish system may be better - maybe selecting a checkbook and then pressing publish (similar to now having to select a box b/f being able to select Reject)

I certainly is simpler to approve a review than disapprove it. If it could be altered to be similar, an inadvertent approve would be far less likely.
