Please note that Folder View is now the default view in Receiver for Web 2.6 for mandatory stores.
Citrix Receiver for Web in StoreFront 2.5 supports a notion of mandatory/locked down store, in which all published applications are available in the Home screen without user subscribing to them. This works well for users who have a small number of applications available to them, however it is not very practical when you have a lot of applications all displayed on the Home screen without any structure.
The good news is that we have developed a customization to add Folder View to a mandatory store, which is available for download from here (MyCitrix credentials required). Please see the readme file in the download package for details on how to apply the customization.
Below are a couple of screenshots for the folder view:
