In the video above in Game Maker Studio 2, maybe one of Mineimator's great programmers will be able to do it

When you press the keyframe and then, for example, press a v, it makes it visible or invisible

Hi guys is a very simple suggestion which is to make the object visibility by the shortcut button or make it in the window listed in time line when you press the click right

It would be better to animate the object without the need to open the folders. When the folders are opened, the timeline is full and it is difficult to control more than one object with the same scene. It would be better to make the control bones like a Blender, I think it would make it easier to create animations and waste less time
