This must be a very noob question, but via googling I am getting different answers.
I just want that via layer panel when I click on any layer,
there must be selection outline between all the layers, that which layer is selected.
I have used Adobe fireworks somewhat, and in it I can easily see the selected layer via just clicking on it.
You can do this by ctrl+click the layer thumbnail, which I highlighted below (cmd+click on Mac)
Don’t click on the layer name, it will select the layer but it won’t show you the outline. Before clicking, your cursor should be a hand with an outline.
Hope this will help.
