One of the features that make Native Cascades stand out from Android ports, as well as from competitors like iOS is Active Frames. Active Frames are a useful tool that can provide important app information to users in the active frames pane on BlakcBerry 10. Information such as recently viewed articles in an RSS feed app, or latest tweets can provide useful information for users without having to enter the application. Developers have the ability to pick and choose what they want to show users in active frames and aren't restricted to one definition or use-case. I personally like to add a nice cover image to the active frame even if I'm not going to invest the time into coding some important information for my active frames. It looks more professional and visually appealing to users to give them that all-around BlackBerry 10 experience.
