What feature do you want:

The ability to look inside chests on plots you don’t have access to, but not alter what is inside.

Why do you think its a good idea:

On plots that you don’t have access to, you cannot open chests, because you could change what’s inside and possibly mess up builds like sorting systems, which makes sense. However, it would be beneficial to see the contents on these plots, but not edit them. If I had a redstone creation and wanted to show what the materials required were, I would want to put them in a chest so that people can open it up and see them. If they weren’t allowed to build on my plot, they couldn’t change the items inside and only view them.
