Next Big Thing.. Playhead

Awesome plugin Carson! I've just been getting rolling with using your tools to create animations. I keep wanting to be able to have some sort of timeline/playhead similar to a conventional video editing. In grasshopper terms, I could set the domain (start time and end time) of my animation, scale the timeline like MD slider/graph mapper, and then click a point or drag to a particular frame to test. I think it's like a 1-D MD Slider component that has a play/pause or just rounds to the nearest frame based on the percentage. I haven't become a coder yet so not sure how easy/hard this would be to develop. I think the concepts/bones already exist in Grasshopper. What do you think?
