Next build there'll be a combo box on the Object Bar to select a layer for which the objects below will be shown.
Could I make a quick suggestion to disallow pasting into a locked layer? Every once in a while I'll have a locked layer selected and all of my paste commands drop the objects in anyway, and I don't notice until later which means I have to clean up a bunch of objects.
Same thing with inserting new objects
Or maybe a little popup that has the options "Unlock Layer" (to continue with pasting) and "Cancel Paste/Insert"
