When making items (in)visible in the Title Editor, you click the eye icon.
A dim eye indicates a hidden item. A brighter eye indicates a visible item.
However, the difference in brightness between the 2 icons is minimal.
Please make the dim icon darker or otherwise increase the difference.
Like using a striked through eye icon for 'invisible'.

This images shows the lack of distinction:
