Batch-Generate Previews is very handy feature for previewing assets when importing / linking, I would just like to know if there is a way to:

 1. Make thumbnails lighter to match the real models (they use Shadeless materials)
 2. Increase thumbnails resolution to get more clear preview when using large thumbnail view in the explorer
