Control Panel - System Status
The System Status window includes the resource monitor and a summary of the system and its hardware, your network's status, and all running system services.
CPU-, HDD-, and System temperatures are a part of the Hardware Information tab in the System Status window. There is also a widget you can drag to the desktop. It will keep track of system temperatures.
Control Panel - Applications
The control panel contains QNAP's Applications menu through which you can install and configure all available QNAP stations and applications. One of the most interesting stations is HybridDesk Station, a platform onto which the famous Kodi (formerly known as XBMC) application and Chrome, along with other tools, can be installed to browse the web or playback NAS multimedia content, via a TV you can connect to the NAS through its HDMI interface. This application will definitely be of interest to home users since it makes multimedia players and HTPCs redundant. That said, HybridDesk Station can still be very useful in business environments since it makes locally accessing the administration interface without a client possible.
App Center
App Center is a managerial platform for installing add-ons. Users can search for, install, remove, and update already installed apps. It is, in other words, like the App Store of Apple's iOS. Applications are separated into categories. There are also lists of QNAP's selected applications and the recommendations QNAP makes. As you can see, the list of available applications is large, and you will find more after only a quick online search. However, you should only install applications that are already verified by QNAP to avoid complications. While their installation is automated, you can also manually install these.
