Add thumbnail for Smooth by Angle

Hello

Ideas

Add thumbnails and tags to the Smooth by Angle node group, and tags to Brushes

Why would it be useful?

In the current Essentials, I guess Smooth by Angle is the most used one. I really like the thumbnails that Blender has made for the brush and hair nodes. Considering the importance of this node in daily work, it obviously makes sense to make a thumbnail for it.

In addition, when looking through Essentials, I found that all Hair node groups have the [Hair] tag, and some node groups have the [Guide Curves] tag. But the brush asset does not have the [Brushes] tag, and Smooth by Angle does not have the [Normals] tag.

For example, we can add the [Brushes] [Grease Pencil Draw] [Draw] tag to the Pen.

This should help keep the assets consistent and easy to use.

Thank you very much for reading to the end:)
