it would be nifty to collapse or hide layers that you don't use in a certain performance.
furthermore it would be very handy to reduce a layer group to only one layer so that all the layers in the group disappear and you only see the group master. with those features you could keep the GUI nice and tight without distracting things.
oooh yes! with big setups it gets a real hussle to handle the layers. I`m missing this function since the stuff with the mapping started. Dear brilliant coders from resolume, I bet this one is an easy one, isn`t it? it would help bigtime!
