(Loop effect) Alternating slides or images with a user defined timer
Sometimes one wants to show differences between two images (representing medical, seismic, physics...). It is uncomfortable to hit right and left arrows to go back and forth to alternate the two slides or images. Even sometime in congress, the joystick given to the talker is not well design for such task. Thus, it would be nice to have the possibility to make loops either between two (or more) slides with a user defined timer, or making loops possible in the animations within a slide.
