As a Roblox player, it is currently too hard to play the mobile version with a mouse and keyboard, the android native pointer by default is limited by the screen borders, which causes the mouse to stop moving in that direction and inputting to the app. As a result, games that require freely rotating the camera, such as first person shooters, have limited user experience. The video below shows this behavior:
If Roblox is able to address this issue, it would improve my user experience because it would offer faster and more accurate movements like on the PC version rather than only using touchscreen, specially when I can plug my phone into a bigger screen.

Some apps, such as games, remote desktop, and virtualization clients, greatly benefit from getting control over the mouse pointer. Pointer capture is a feature available in Android 8.0 (API level 26) and later that provides such control by delivering all mouse events to a focused view in your app.
