Moving the SF folder into Standard Assets

Not sure how self-contained it is, but when I moved SF into Assets/Standard Assets/ShaderForge/ (setting up Perforce and using SF as a possible tool that would be distribution across the team), I get this error popping up and a blank editor window:

NullReferenceException: Object reference not set to an instance of an object

ShaderForge.SF_Editor.DrawPreviewPanel (Rect r)

ShaderForge.SF_Editor.OnGUI ()

System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) (at /Applications/buildAgent/work/b59ae78cff80e584/mcs/class/corlib/System.Reflection/MonoMethod.cs:222)

When in it's regular /Assets/ShaderForge/ location things are fine. I haven't tried other locations yet though (like I said, still testing and setting up P4). It might be due to the special nature of the Standard Assets folder however, so I might have to set up an additional non-special folder for project and team distribution of global stuff.

But it's just something to look out for, as I like clean setups and would prefer that all extensions reside in the same place as not to clutter the project but still make it easy for distribution.
