Hey Ding
I know how it goes two steps forward three back

been there actually that project makes me jealous I would love to rebuild a house like that give me a break from the Ford

talk about some one taking forever to get any thing done on a car I am sure I take the record.
The House is really looking good You have to look at what you started and when? It wasn't all that long ago when you started.
Have you thought about all new electrical and new plumbing yet? before insulation and Sheetrock? I would do all new at this time.
Probably all new heat and air as well.
Don't worry about that finger it'll feel better when it quits hurting
What was the major cause to the second floor sagging?
Did you find bad wood or was the foundation movement causing it? or was it a combo of both?
I like the French door job looks tons better than what you took out.
