5. The haunted house will be a rabbit hole just like the Sims 3.: Yeah, I can't see that being active, sadly.
I saw on the trailer that the haunted house looks like it's a rabbit hole indeed.
6.Only one special window from build buy will be functional for sneaking out not all windows will be updated with this feature. Agreed. Again there is a parallel to werewolves with the werewolf only door, this would be something similar
I guess. This is kinda obviously true. James Turner also speculated this.
7. You cannot raise the window to get fresh air it’s only functional for sneaking out or sneaking in and I believe that will only be limited during certain times of the day or night I'm hoping that's something we could at least do with the window for sneaking, but if you can open them it will only be with windows from this pack so hopefully they have a more universal styling that can work in a lot of different building aesthetics.
I think I saw a sim sitting on the window, like on the windowsill. So I guess it's not only for sneaking out. But I agree I wish we can do more with the windows, like stare outside and think, open for fresh air etc.
