Hi Daniel,

Something that I would really appreciate is the ability to "lock" an entity in the database tree, as in you cannot apply any edits to the cloud. I frequently end up picking the wrong cloud and move the wrong cloud, or do some other interaction that wasn't intended. If there was a toggle or some sort that I could mark an entity as "unmovable" that would be very helpful.

Ah that's an interesting idea, I can add that to the TODO list.
