Hide "hidden" layers in timeline

Hi all,

Do you know if its it possible to filter and hide all layers in the AE timeline which i've chosen to NOT to show and beeing visible.
That would make my timeline much easier to overlook. Now i've tons of experimental layers which shows in the timeline, but are not active.

Instead of showing me 200 layers, AE could just show me about 50 layers which are active and visiable (eye logo). 

I've attached an example image.
