Class dot behavior

By looking at the dot next to the class name, you can tell if a class has been drawn in a 3D semantic segmentation task.

When a class has been used, the dot next to the class name shows the class color. If a class has not been used, it will be greyed out.

When you hover a class that has been drawn, the icons for lock, hide and delete will be shown, read more under Class functionalities.
