Improvement to hiding layers.

I have multiple layers. Layer 0 contains a shadow station. Layer 1 contains visible track and landscaping features, scenery etc. Hiding layer one hides track/scenery, but:

• landscape remains visible, obscuring the view a bit
• when dragging to select a section of track in layer 0, track in other hidden layers gets selected too

As before, kudos for the great tool and process around refining it - especially for a MacOS user <3.
