Hi @Gail1
Welcome to the forum and thanks for sharing your idea! 
Each sit can have it’s own quirks, as each home, pet and location is unique. But having a consistent foundation can be useful.
With that in mind, yesterday, we introduced our pre-sit checklist which covers some of your suggestions, and in the near future, we’ll also be introducing ‘check out tips’ to support the sitters departure.
All the best,
Mark.
