Post Manager is your main screen where you navigate through all your created content.
When you login to Studio, you land directly into the Post Manager - otherwise known as the 'main screen.'
From here, you can organize your Posts by moving, deleting, or duplicating them. Also from the Post Manager, you can create new Posts, create new Categories, filter your Posts by archived and scheduled Posts.
The Categories (folders for the Posts) are listed in a vertical orientation for easy navigation of content within Studio Post Manager.
Select the the ellipsis icon (3 vertical dots) to Archive or Rename the Categories. The Categories are shown in alphabetical order.
