I thought I had added this to the docs a few weeks ago, but as it turns out there are 2 places that talk about the flowgraph editor.

I second this. My main project exists out of 3.8 GB of sound and that is just speach and not even music. I think ogg support is something that should be part of the core leadwerks functionality.
I have rewritten FlowGUI entirely with panels, buttons, checkboxes, sliders, text areas, textboxes and dropdownlists. I am waiting for the Steam workshop to accept payed items though. Depending on its popularity I want to expand it even further.
This is what happens in the beta: You create items or duplicate items. As soon as you make them a child of some other entity, it looks like everything is okay. However, save your scene and reopen it. Your child items are now no longer in your scene.
That is also the reason the scripts are failing. Those entities are actually nil.
There doesn't seem to be an option for it in the editor. Seems like something we need to request.
In the mean time you can edit the .mat file in notepad. Simply remove the line containing the shadow shader.
I have added them to the documentation, although I do not know what the xbuttons are.

I am working on adding these to the docs. I am checking with Josh which ones are official and which are not, so I am just adding the ones that Josh gave the green light for. So far added:
virtual int GetLightQuality()
virtual Vec3 GetGravity()
virtual void SetGravity(const float x, const float y, const float z);
SetLightQuality example added
It has happened to me that the window is hidden in the sides of the script editor. If you move your mouse closely to the edges of the editor, you can find it again.
Some mouses have extra buttons on the side, maybe that is what they are.
These 2 pages are now updated:
