When creating your posts, you might go through different versions of copy or media. In Planable, you have access to all changes made to each post.
Open any post in a new window and select "Activity", right next to comments. You'll find there all of your post's history, edits, and who made them.
If you want to see a previous version of your post, just click "preview". Think it sounds better? Easily "restore" it.
