Solo Mode

If you click any of the icons in the column next to each layer in the Page & Layer Gallery , it will 'solo' this layer which means it hides everything else, except this layer. You can now work on this layer in isolation. Clicking the icon again will restore everything back to how it was before.

You can also click and drag down the column of icons to quickly browse through the layers in isolation from everything else.

To exit the Solo mode, click the button again.
