Point clouds need to be included in a category for "hide by category"

[JD3D_CGI]

This one doesn't need that many votes because it seems like a simple enough task.

Right now I can't even hide layers with them on. They are just always displaying.

You can add it yourself, save this as a .ms file in you scripts/startup folder and you will have a PointCloud category where IK Chain Objects and others are listed:

fn isPointCloud obj = isKindOf obj PointCloud
registerDisplayFilterCallback isPointCloud "PointCloud"
