One of these changes was replacing the last home screen page from spotlight to the new Today View which features the date as well as some widgets which may not be particularly useful.
Spotlife, which has nothing to do with Spotify, changes this back to the Spotlight page which may be more useful and effective for some people. The tweak is surprisingly smooth and stable, which makes me believe that the code for the Spotlight page may still be present in iOS 10 and this tweak doesn't add this functionality back but rather enables it.
The tweak is available in the BigBoss default repository, which means you don't have to add any additional sources. It's even free which is also very welcome in the world where most tweaks, no matter how minor, have a price tag next to them.
