This is an excellent product allowing you make to make main lists with sub-lists where needed. I have hectic days and it helps me to remember what I have to do and keep a track of all the small things. Would love if lists could be shared with a someone and also an export to a chat (whatsapp) would make this a 5 star product. Thanks for the info Steve. Just rated you as 5 star. That does help me a lot and I'm sure many others as well who use WhatsApp.
