I've just had an amazing conversation over in the python forum where HartyBart and Y-Phil came up with some solutions.  Y-Phils dynamic dialog box works wonders as you can see...

Now these readme popups can let me add more info to a specific folder rather than the tiny 91x91 png files I used to use to add notes on how/what to parent figures to in each folder. woo-hoo!

Here is a link to the thread:

Thanks for all your input guys!
