To keep things simple and ensure the clock widget looks good in combination with Niagara Launcher's other inbuilt widget (like the date, weather, and calendar widget), we decided not to make our clock widget customizable. However, you can replace the clock with a widget of your choice:
It should be noted that one can only have one custom widget displayed at once. Since we are making use of this feature, you have a modified clock and display another widget simultaneously.
- Go to the bottom of the all apps list > Niagara settings > Features > Niagara Widget > Add custom widget.
- After choosing your widget, long press on it on your home screen and tap on "Replace clock with widget."
- You can also make your own custom clock widget using the app KWGT, for example.
