Top layer is super annoying

Hi, I often like to hide layers to perform experiments on my piece. Unfortunately, I often mistake the over-layer for a regular one, because it looks exactly the same. So I click the eye and it makes all of my hidden layers visible all at once.

Can you please change the color of the icons? I thought that I had saved my work and could re-open, I lost a lot of work. I know that there are work arounds and that I should be more organized, but it’s just good design.
