Hi all,
Sorry for not replying sooner, work got in the way

As for GUI updates, the only ones I can remember are:
How to read entry from Input Box when ENTER is pressed?
Rotate images in Buttons as they currently seem to be rotated 180 degrees
Enable / Disable GUI elements
ComboBox options (i.e. populate / getSelected / setSelected)
Radio Button options (i.e. setChecked / getChecked / setText)
Slider & Slider options (i.e. getValue / setValue / setMinimum / getMinimum / setMaximum / getMaximum)
HTH

PS: Any chance I can also request some way to set the Specular &/or Diffuse via code for individual Models (if it's not already there and I've missed it!)?
