Hi Danny, one thing that will probably come in handy for you is that type label in the upper-right corner just to the right of the name.

When you have an object selected that has all joined edges, it will say "Solid" over there so that should be a quick way to tell if your object is a full solid without needing to do any other steps.

That "select naked edges" script will still be handy for the case where you don't have a solid and you want to see where the open edges are, but you won't need to run it just to see if something is a solid or not.
