I notice it is very difficult to find what prop is listed as and what does what when you have almost a 100 props.

It would be nice to be able to divide them so I can put all of 1 type of prop into a subcategory.
To be able to lock a subcategory and set its visibility would be very useful for a set of props that would not be needed for example: the alternate view camera angle.
Then I can make a new subcategory and call it "Dummy" and place all dummy props.
Then I can make a new subcategory and call it "Emit" and place all emissive props.
Then I can make a new subcategory and call it "Interior" and place all props used indoors.
Then I can make a new subcategory and call it "Exterior" and place all props used outdoors.

It would help so much to organize a large amount of props.
