horisontal door

Hi.

I think the door is also rotated clockwise visually.
The big part (bottom part on vertical door) is on the left.
The small part (top part on vertical door) is on the right.

The door's artwork looks the same whether it was visually rotated 90 degrees clockwise or counter-clockwise. You can't use the S-shape in the middle of the door to judge that, since it'd be a left-to-right move either way.

 

The main key to look for when rotating a door horizontally is where the blueprint is centered before placement with the mouse cursor. The bottom tile becomes the left tile, indicating that the door rotated 90 degrees clockwise, and the permissions arrows indicate that you're going "up" and "down" respectively.

 

I had to draw the mouse cursor back in in since screen-shotting it hid it, but the cursor is the center of the rotation, you see it rotated clockwise.

That said, it'd be nice if the permissions window rotated the arrow indicators to make it more obvious.

yea i guess i can see now, but its rly not easy to judge
