[Feature Request] Overlay Item Placement & Animation Customization

[RyeMoes]

Describe the solution you'd like 1-Instead of having to set X pixels, an extra option to set X percent instead. "75% from the left, 15% from the top" to have image show in similar location regardless of canvas size.

2-Allow "Random" Animation from drop down for Entrance, Exit, etc animation options.

Additional context This would allow quick and easy placement without having to go pixel by pixel and also allow variation on the way things appear on screen without having to manually code this.
