I have the need to back date a bunch of posts and flipping through the date picker for scheduling the post is a bit cumbersome. There does not seem to be a way to just type a date in. 
Is that a setting I can adjust somewhere?
Hi Joey, at this time, it's not possible to type the date into the calendar. The feature is read-only.
Is there somewhere we can make suggestions?
Certainly! I've added your suggestion to the feature wishlist.
