Apologies in advance if this has been asked for already.
I usually write posts for future publishing. Invariably, when I finish a post I forget the dates that other posts were scheduled. I have to save my work, then go back to the Posts/Posts page to check the dates that other posts are scheduled, then go back to the Edit screen to schedule my post.
What I would love to see is a calendar (in the right sidebar) on the Edit page showing the current month's (by default) published and scheduled posts, so I wouldn't have to switch screens.
Obviously I could just check beforehand, but sometimes I sit on the Edit page for hours and by the time I finish, I don't remember the posting schedule.
Thanks for your time.
