Quick Guide

1. Select those polygons that contain the points you want to move.

2. Select the points.

3. Set a translation offset.

Usage:

The initial polygons selection allows you to decide which normals
are going to contribute to point normal movement.

Example:

Axis constraint blocks each point normal component separately.
If you want to move a couple of "rows" of points along the
computed normal but not on the Y axis, just uncheck it.

By clicking "Cancel" all the selected points positions
will be restored (built-in undo), but the applied result
can't be undone using standard Undo command.
