Mini widgets. Its between complications and duo widget, it has as small size, as your complications, but it will or replace complications, or it will be available when there's no mini widget, as you wish

Mini widget could show ongoing timer when timer widget isn't open, music thumbnail, and visualization (as settings set)

It can show weather, it can show time in different city, or even weather in other city, it can show soonest events from calendar, date, it can show what complications can show: welcome text like "good morning", battery level, inspirational quotes.

It can have interactive actions, imagine staying on digital clock in full screen for example, but have quick access to timer, music, battery. And info at just a glance but still keeping gorgeous clock edge to edge.

And finally, it will have very rounded corners, and will be available on top and bottom center, or top and bottom in left or right corner
