After successfully attaching media, it was not clear to me that clicking on the media would remove it, which could be quite bad if the user is taking photos or video live. I had suspected that after attaching, I would select media that I wanted to include or exclude (which would be indicated by a checkmark), which I think would be preferable than the media being removed altogether
