The /mode observe command would allow you to observe other residences on SMP towns in fly mode without being able to place, destroy, use other commands, make shop transactions, open chests or even talk. It would purely be for the use of observing residences with the speed set to below walking speed.What about all the people that will think that you're using illegal mods and end up reporting you, you might ask? Well, the players in observe mode would be invisible. /res pset/set fly false would work alongside this command, giving res owners the full option to turn it off/on.It's a nice compromise between a french-vanilla legit server and having the ability to fly. What are your thoughts?Addition: When /mode observing back to normal you will be in the same location that you activated it at.
