A new jailbreak tweak called 3DLight brings opacity to widgets and 3D Touch menus in iOS 10. So if you want to add some light changes to your 3D Touch menus and the widgets look in Notification Center and on your Lock screen then go on reading this post.
How To Bring Opacity To Widgets And 3D Touch Menus
3DLight tweak brings a purely aesthetic change as you’ll see from the pictures below. Here you can compare how the tweak changes the widgets on the Lock screen:
The next two examples show the way 3DLight changes the look and style of the widgets in Notification Center:
As you can see all of the info remains as legible as it was before tweak's effects, so you've just get a slight style change. What's more important, your iPhone’s system resources now don't have to blur any of the content which appears behind your widgets or menus.
So if you want to bring opacity to widgets and 3D Touch menus in iOS 10 you should navigate to Cydia’s BigBoss repo and download 3DLight tweak for free. It doesn’t offer any options for configurations and it supports only jailbroken iOS 10 devices.
3DLight tweak works with third-party Notification Center and Lock screen widgets that are available for download from the App Store. It also works with devices that don't support 3D touch feature as long as some 3D Touch-simulation tweak like Peek-a-Boo (by developer Creatix) is installed on them. Don't forget that tweaks like RevealMenu or Forcy haven't yet been updated to support iOS 10, so they are not compatible with 3DLight.
AS for me 3DLight is interesting tweak, so if you prefer opaque look more than the typical transparent one, then you should give this tweak a try.
