I’d like to see the ability to move a layer along a CURVED path rather than always in a straight line, while still keeping the ability to rotate the object while it moves.
The ability to create bezier curves (ala Adobe Illustrator) would solve the problem.
Circular movement “around” the slide, arc-shaped movement across the slide, S-shaped movements, even the illusion of an item “bouncing” across the screen (using upside-down “U” shaped arcs). You can make an object move in a rectangular fashion now, but it requires 4 separate slides in sequence, moving from one corner to the other for each side, and with a “cut” transition between the slides.
