This is a request to the programmer of SMBX for the next SMBX update. Since I have a camera issue while the screen splits during multiplayer, that is I can't see much vertically during horizontal split-screen and vice versa, I would love to have a new key/button for scrolling the camera.
So when the screen splits vertically, players would press the camera-button to scroll the camera to where the player-character heads.

As for the horizontal split-screen, players, may want to press the mentioned button to see what's below them; and hold up and press that button to see what's above them.
Thank you for your understanding.
