Update: Celsius is updated, so everything should work as intended now.

1.6 update for use without Celsius (it wasn't updated yet). If you encounter any errors, please let me know.

@Seripa You can use it without, only the heat conduction won't work. I'm not well-versed enough in C# to set that sort of thing up on its own.

I really like your mod, but Celcius is absolutely terrible.

I should have made clearer that I was talking about XML-only possibilities. Stall doors work the way they do because of C# coding. That sort of thing is (mostly) still beyond me.

hey, in dubs bad hygiene there is a bathroom door that doesnt seperate the rooms it is build in (just adding this because you compared this to other mods)

this is amazing! Just wish there was a version of this that works like the embrasures mod, where you can shoot through these grates. they also allow heat to pass through, tho they don't seperate rooms unfortunately.

@Pudding Deity The mods that I know which provide windows and embrasures are in part coded in C#. The restrictions I mentioned apply to an XML-only mod, which this is. Maybe I should have made that clearer.
The aesthetic was part of my motivation, and more freedom to divide rooms. (The rec room/corridor thing mentioned in the description always irked me a great deal.) I see benefits in the room stats, like when cleanness affects meal quality, research speed or infection chance. A smaller grid-walled hospital room is easier to keep clean and to floor with few resources than if you have a hospital bed in a corner of your larger multi-purpose room, or if you need to heat/cool and light an extra hospital room. Also, you can have single bedrooms instead of baracks and have an easier time heating/cooling them.
I'd say grid walls are most useful in extreme climates in the early game when resources are sparse, and they become more about aesthetics in other cases.

Given embrasures and windows are both a thing, and I've seen both be able to enclose rooms, you should probably talk to someone who's made one of those about how to remove celsius as a requirement.

That said I'm a little confused about the actual use case for this. Regardless of what room something "counts" as when you check its stats all the moods and everything else work as normal. Even if your dining room is also a rec room people still get the moods for both. Not that I couldn't see using it for aesthetic purposes, I'm just confused since the description seems to imply mechanical benefits.
