Anything you move into the Media Folder will show up in the Media Panel when the Media Panel is active.
Be aware that the Media Folder will still show up in your All Panel, but you can Hide the Media Folder icon there and the apps in your Media Folder will still show up in the Media Panel.
select the media or app you want to move use the bb button and move to media. Now it will be in the media file and also in the media tab.
I figured that out...sometimes you miss the simplest things. I was fixated on the panel and forgot about the media folder that I've only been using for about 4 years!
