Q: Floor "Thangs" not the right default size - should they be fixed?

@Bryukh Thank you for all the help so far.

@Catsync @maka First of all, thank you for taking the time to respond.

So then the question would be:

Q1: If I updated each floor Thang to follow the dimensions that exist currently would that be helpful?

.

Q2: Also, now that I have your attention, what about creating new Thangs? How should one go about doing that?
