Even though this widget was first published on 1st of April, this widget is not a joke. It is but it is not intended as April Fools. It's just a coincidence. And we all know there are no coincidences.
The idea behind is simple. We're always running, we always need all the information we can have at once. Time with seconds precision, all the tasks and meetings planned for today at once glance and all the important messages awaiting for response. That's what widgets, especially the lock screen ones, were made for, right? I don't think so.
This is a memento mori widget. Initially it was planned as lock-screen-only widget, but my kids don't have the 4.2 yet and they already asked if they can have it.
So it's now lock-screen-also widget telling you what is really important in my opinion. And you can even adjust the level of details.
In Importance widget Musesv2 Support for devices as back as Donut. Optional black background. Some magic.
