Screenshots
You can use right-click on Game window tab to take game viewport screenshot (saved inside Screenshots folder in project). To make higher resolution screenshots (eg. for marketing of your game or project) use Viewport Resolution and scale up the window backbuffer (eg. by 2-4).
Utilities
You can use right-click on Game window tab to show or hide game UI or DebugDraw shapes.
Game viewport sizing
Right-click on Game window tab to use Viewport Size submenu to override viewport aspect ratio or resolution. For example, it can be used to test cut-scene animation in 16:9 aspect ratio or to test mobile game viewport on iPhone or Android devices. You can use predefined viewport sizes or add custom ones.
