I had someone take one of my maps, re-name it, and upload it as theirs before, so I always password my maps. Why would you need to see it in the editor, vs. in-game flight cam?
Nobody will take your KO maps and reupload them as theirs, but you can continue to password your other maps of course.
I mainly use the editor, because I can look around the map a lot faster and start driving from anywhere. I want to make sure the maps are not only respawnable, but also finishable after you made a mistake and
don't respawn. Respawning shouldn't be a go-to choice for the tiniest mistake. I can also build suggestions for changes etc in the map, if needed.
