Additional Functionality To Tailor Email Notifications

These may have already been raised before but the following additional functionality would be useful. FEATURE 1 - To be able to configure the stores so that only price change emails are sent from the stores the user wants updates from e.g the user doesn't have a Waitrose nearby so does not need an email notification saying the price of Baked Beans has dropped by 25p FEATURE 2 - A follow on from "FEATURE 1" for each product notifications add an additional column displaying which store (out of the user selected stores) is the cheapest place to purchase that product from e.g Sainsburys may have dropped the price of Tomato Ketchup but Asda is still cheaper. FEATURE 3 - Have the option to recieve a separate email price notifications for each of the users selected stores e.g. 1 email for Asda, 1 email from Morrisons etc. FEATURE 4 - Have the option to recieve product price notifications grouped by the User created Favourite Lists. I currently use the Favourite List functionality to group similar products together in specific lists e.g. "Frozen Food" , "Sweets And Cakes" having a separate email for each of my Favourite Lists would be useful
