The Content Manager page is where you can edit the layout of your store, pin things to the top of your page, edit and delete Vids or Store Items, see vids that are set for future release and more! To find this section of your account, go to the drop-down menu > My MV > Content Manager.
To utilize this page, first select if you want to edit Vids or Store Items at the top. If you want to reorder things as they appear on your profile, hit "Reorder" and then you will be able to drag things up and down the page to select their position, then hit "Save" when you're done. To move a vid from page to page in your content manager, you will need to turn off "Reorder", click the 3-dots to the right of the vid and move it ahead or back one page (you will only be able to move it one page at a time).
If a Vid or Store Item appears on a different page and you need to move it, leave "Reorder" mode and click the 3-dots to the right of the item you want to move pages and you'll see the option to move it ahead or back a page.
Clicking the 3-dots to the right of a Vid or Store Item will also give you the option to "Pin" items to the top of your profile to make sure they always appear first (click the 3-dots again and hit "Unpin" to unpin the item), the ability to Tweet to promote that item (if your Twitter account is connected to your MV account), edit the details of that item or to delete it from your page completely.
To view and edit your vids that are set for future release, click where it says "Launched" and change it to "Scheduled".
Feel free to play around more in this page! It's a great way to see your sales, views and likes across all your Vids and Store Items to determine what works best on your page.
