Hi Danny - I think what you want there is a "show naked (unattached) edges" type thing.

I haven't quite decided whether that would go under "Analyze", or as a "View" type thing to show naked edges in a different style somehow.

But one thing that is really easy for me to do is to add some scripting properties so that those edges can be identified to a script, then it will be possible to make a keyboard shortcut script that selected all naked edges and that would be a quick way to get this function enabled in a basic but useful way for the next beta.

re: solid versus sheet determination - that is something that I want to show in the object properties panel, so that one is part of the batch of object organization tool work.
