Notes on Items and Assemblies

You could create a custom Property and associate it to all items. then whatever you create will have the property.

I actually thought of that as soon as I hit post. :-) Thanks for replying!

It would be cool to have the ability to included screen shots or images that show the user what the inputs are supposed to represent.

that would be a good idea, maybe have a circled "?" and when you hover over, the screenshot would appear.

Exactly!
