I have lurked for a long time and finally thought I had something to contribute. Here is a little something I made using the slider feature.
Some things I learned.
1. design a button that can be saved with a transparent background. I did not try removing the background in Powerpoint but that may be possible.
2. The button hole needs to be saved SIDEWAYS so that it appears as a vertical image in the slider background.
3. Create various states for the tag. Name the state 1,2, 3, 4, to the maximum steps of the slider. Obviously the more states you have the smoother the card will move out of the pocket.
