It is driving me crazy that in the newest versions of WP, it's now necessary to set the featured image as a completely separate step from inserting an image in a post. (By which I mean, I used to be able to do this while I was still in the image dialog. Now I have to open it twice.) This seems like a huge step backward to me, where I used to just be able to click an extra time while inserting my main photo, and now I have to go through a whole process a second time.
Is there a reason that the redesign for media uploads/insertion made this more work than it used to be?
