You can change the titles and descriptions of your apps. Click on the app you want to edit and select Rename. You can also change the tags used with the app. Tags are used to group apps with related apps in the cloud hub. Tags are shared in the cloud hub, but you can only see tags that you have created yourself or that are used with apps to which you have access.
If you have access to spaces, you can change the space in which the app is located. Click on the app and select Move. For more information about working with apps in spaces, see Using apps in shared spaces.
