Well, a long time ago I wrote a script to isolate a figure in the scene, an idea I got from watching a friend work in 3ds max, you hit isolate and all other figures and props are hidden, hit it again and they show back, useful for making quick adjustments.

I would like to store the figure state (if it's isolated or not), which figure it is, and a few other options and parameters. I'm storing it in text format right now, but is a clumsy solution, I know there are ways to save this parameters within the poser scene, I've seen it done, just have no clue of how :P
