Yogi, it's a good idea that new vicars get to know their church and the people rather than just taking over. Although there are refreshments in the church hall after the institution & induction service (that's the extremely formal service where the new vicar is made the vicar), the service is so heavyweight and the numbers of people attending are big, that the new vicar has no chance to get to know people at that stage.
Did you have tea and refreshments after your Sunday service today, where she could chat informally to people?
Yes, we did. I was chatting with other people and needed to talk to the curate, and by the time I had talked to her, the soon-to-be vicar had gone. She may well be there next Sunday - I think it's likely as today was the monthly less formal serice and next week is the main communion service which she won't have seen how our church does it. Althouhh communion services are fundamentally the same across churches, every church had its own variations. The style we currently use was created by the retired vicar, his predecessor had a different style, and there is no reason to expect the new vicar to keep to exactly the same style as her predecessor. Although many people don't like change, churches which stick rigidally to the same style for decades can risk becoming stagnant. She may decide to stick with what we have got because there is quite a lot of variables built into the service which reduces the risk of stagnation, but it is her church and she can and will make whatever changes she wants to. Though I think she is sensible enough to wait, observe and discuss before making any radical changes.
Yes I visited MIL tonight, she was much brighter today! It's so up & down that it makes your head spin 
I cut her fringe and pinned back some of her hair, it's freshened her up lovely
