Which properties?

DescriptionFrame is one I remember. Since my 2) above is possible then I'll make some more runs.

 

[Veracity]

That, and others, were added (yesterday) as "built-in" in revision 17896.
Update.

 

[fronobulax]

and _circleDrumUsed

Everything else that persisted after I thought it should not seems to have gone after I logged out and then back in.
