If you've been scheduling a lot of Posts to a lot boards, you've probably noticed that your queue looks pretty inorganic because the same Posts are back to back. This is a good time to try out Drag and Drop to easily re-arrange the Posts in your queue so you aren't posting the same Post so many times in a row.
Go to the Drafts page (located in the pop-out menu in the left hand navigation).
2. Within the Your Grid section of this page, click and hold any Post to drag and drop to another timeslot. Try dragging a Post to a future date or drag a Post from the future to today. Magic. (You'll also notice the posts under the Your Post section will re-arrange according to the order to place them in on the Grid.)
Unlocked Posts will shift around the newly opened time slot to fill in the gap.
You can even drag and drop a locked Post, and a Post that has been manually scheduled!
