CoolCC does away with the dark Control Center module backgrounds and surrounds each module with a subtle border.
And in case you were wondering, CoolCC plays nicely with full-screen modules such as Now Playing and other add-ons that you might install from Cydia to complement the Control Center experience:
As a minimalist, I must say I adore the look and feel of Control Center after installing CoolCC. Its effects aren't overwhelming; instead, they're somewhat subtle and enjoyable.
The tweak doesn’t come with any options to configure, so what you see is ultimately what you get.
If you’re interested in trying CoolCC for yourself, then you can download it for free from Cydia’s BigBoss repository. The tweak only works on jailbroken iOS 11 devices as it relies on the redesigned modular Control Center interface to function correctly.
