It would be really nice if we could organize items in the explorer by differently than it does by default. Adding the ability to control how the Explorer sorts items, whether it's something typical like alphabetically by name or something different like grouping by level, would help find things a lot quicker.
Explorer sorts terrains by feature definition. Sort by terrain name instead. Feature definition is property of a terrain that can be changed.
I would like to see the ability to sort Drainage and Utilities elements, too (nodes, conduits, etc.).
