My suggestion for New Content is a so called Dementia clock, for people with failing memory, such as my father. These are available on Amazon etc.. but are a bit ugly and are not configurable. They show the time of day as well things like 'It's Tuesday Evening' for example.
There are lots of examples using this library on YouTube, but all just use the supplied example code with minor tweaks.
If we are programming the code ourselves we can add custom timed messages like 'Take Medication Now' appearing at a certain time of day etc.. The clock could mostly show the time of day (not scrolling) and periodically show timed messages scrolling along. You could use the MD Parola library to add transitions such as scrolling up between messages.
I'm sure many people would find this interesting and of course the code can be modified in many ways.
