This is exactly the kind of toolset I wish more people building for Unity actually understood the point of. The bottleneck for an environment artist was never the modeling or the composition — it's everything around it. The constant context-switching: stopping to untangle a messy hierarchy, chasing down a broken reference, renaming the same batch for the tenth time, fighting placement by hand. Each one is small on its own, but together they quietly eat the day and pull you out of the headspace where the actual art happens.
What I really appreciate here is that it keeps me inside the Scene View, which is where I want to be. The whole philosophy feels like "let the artist stay an artist" — hand the repetitive, organizational housekeeping over to the tool and keep your head on mood, layout and the feel of the space. And when a toolset does its job right, you almost forget it's there; you just notice the friction is gone and you're moving faster without thinking about it.
As someone who writes a fair amount of my own editor tooling, I know how much care it takes to get this feel right — fast, non-destructive, out of the way, instead of another layer of menus to fight. This nails it. In practice it means the overwhelming majority of my energy goes straight into the art and only a sliver into the plumbing, which is the entire point. Really solid work.
