Though the store navigation looks and feels half-baked in comparison to the old Windows Phone app store. If you are on an app page there is no clear way to find your way back to the App store home. Search works for entire Microsoft.com, while it should have been limited to app search in the store. Perhaps Microsoft needed to think about the website design basics before launching the Universal app store. The top navigation menu is entirely missing.
Also there is no way yet to see when the last update has landed for any app and you can’t see all apps that a publisher has got by clicking on its name. Even the features like downloading XAP files manually or remote installation of apps is not possible now.
