Each page has two orientations, Portrait and Landscape. Portrait mode is defined as the orientation where the height is larger than the width, and Landscape is when the width is larger than the height.
Depending on the Viewer software being used, the page orientation will automatically rotate to match the orientation of the device. This is true for Apple iOS devices, such as the iPad and Android devices.
To stop a page from automatically rotating, all you need to do is ensure you don't have any GUI objects within the orientation you don't want to rotate to.
To add a new page, just click the icon from the toolbar.
When the project is loaded for the first time, there's always a need to show a page as the default startup or home page. To assign any one of the pages as the start page, just right-click on the page icon in the Project Manager and select “Set as Start Page”.
