For some reason UnionOperations / MeshParts are currently sorted on top of Models in the explorer. This is a weird behavior because these are still individual pieces whereas models are collections of pieces so it doesn’t make much sense.
Example of strange behavior:
It would be ideal if they still were ordered above parts, but below models!
I remember this being suggested back when the Trello board was still a thing; for some reason it didn’t get implemented and was put in the ice box? Anyway, this would be nice. Container-style objects should always sort before others.
You can accomplish this behaviour using Reflection Metadata in the meantime; however the documentation on it was removed from the rbxwiki about a month ago.
As nice as options would be for everything in existence, that sounds overkill for something like this and out-scopes what would be a simple change into a larger task.
We need a default that makes sense and is easy to use.
