Describe your suggestion

Hammer++ has a feature where the texture application window has a button that makes all selected faces nodraw. This is very convenient when texturing brushes, and I miss the feature in Strata Hammer.

1. User selects whatever faces of a brush they want
2. They press the nodraw button
3. The faces are made nodraw.
