I agree with karlie about getting the information from customer and save it into customer note field in admin dashboard.
If you want to save more information like 'your customer viewed products', 'your customer Wishlist'....etc., You can try our app "Tuecus".
And we design easy way to use of "customer dashboard".
Simply Tuecus gives you a proper overview of your customer's actions on your website.
