Widget to display a schedule, list, or ???

How about a (large, maybe even full phone screen size) widget and hashtag that would let me display a to-do list, a shopping list, or a day's agenda on my phone screen for immediate or one-tap display? I've seen other suggestions about the option of sending/saving to a device, which is also a really good idea, especially in areas like mine where internet access is spotty. The widget and option of sending to local device could work together. Right now the only option is to send the PDF to its destination and then screenshot it or download it to the device. Which still requires a couple of clicks to get to the storage and display it.
