I have moved this topic from #wishlist to #ask-the-community for now. Submissions for #wishlist need to be single-subject so they can be voted on individually.
For #1, that can already be done by using the Shortcuts feature in the app.
For #2, I’m not sure what you mean here. A much more detailed explanation is required.
For #3/4 they seem to be the same thing. Please submit this as a separate #wishlist request.
