This wasn't missed...it's on the list but there are some other items we want to get done first. Rest assured we have it down as something to look at. That said, it's not a simple fix. (I know this as it was one of my suggestions early on...) The calendar control that's used has certain editable areas and certain un-editable areas. We'll need to put some time and effort into making the All Day area sticky. Not saying it won't be done, but wanted to put the change into context.
