Hi,
Is there a way to make the medial/subcortical view a little more presentable? The default seems a little hard to make it. Can it be smoothed?

Not sure what your definition of presentable or hard is. Can you upload an example. If you want a 'smoothed' medial view I would do this:
 1.) Drag and drop the "BrainMesh_ICBM152Left_smoothed.mz3" onto surifce
 2.) Choose Display/Right menu item to show the medial view
 3.) [opetional] choose your overlay volume or mesh (for the image attached I selected the "motor_4t95vol.nii.gz" and set the overlay threshold (for image below I selected 1..2).
 To show the medial view of the right hemisphere just load the "BrainMesh_ICBM152Right_smoothed.mz3" and choose Display/Left

 You may prefer MRIcroGL's volume rendering to SurfIce's surface rendering - they are suited to different tasks and do have a different look. In particular, showing subcortical structures is often a good task for a volume renderer.
