Contextual Icons in Layer Control

When lots of layers populate a Layer Control drop menu, it will be good to have icons such as Lock, Visible Shy - will be much quicker to make selections since it's quite often layers that are lumped together have similar names.

Also, if I accidentally hit CTRL + SHIFT + W, is there a way to at least get the last comp/timeline I was at, and/or is there a Toll-free Number to call for assistance? If no, then this is not a good shortcut to have cos it's quite disruptive.
