This has been a real problem for me also. If you have groups within layers and you need to unlock an item within a group it can take a lot of time to find the item that is locked.
There should also be away to click on a lock object and quickly find that object in the layers panel, right now if you lock an object it can not be selected again until you unlock it from the layers panel. The object should be selectable but still locked then a "Find in Layer" command could take you right to the lock object in the layers panel.
I also miss the "move to layer command", this really helps when you're trying to organize a project.
