Agreed, this is why I just don't use door partitions at all.
I'd love to use them, but the shortsightedness in the design- the shortsightedness in the entire decorating system- is what keeps things so limited.
All I can say is stay persistent on those topics

Story time: I submitted a very detailed 'bug' report on the round stained glass window (it's called the Imitation Stained Crystal Rounded) & how it did not have the same lighting on the stained glass windows that came before; & at night the window darkened instead of stayed glowing/ hazy. I still have screens to show the differences between all of the stained glass windows before. Now, the window glows at night & cast a reflection just like the other stained glass windows. So, you CAN make a difference just need to put in some effort to see the changes you want.

I've wanted a door partition that is dyeable or can have wallpaper placed onto it- Someone needs to take a thorough look at the housing items & work on revamping the entire decorating process from the UI to how items are placed, item limits, how they're dyed, separating lighting per floor as well as music... just everything.
