Thanks to CoolStar & Jeremy Goulet, ClassicFolders 2 now supports to bring back iOS 6 folders to  iOS 11. If you have bought ClassicFolders, upgrading is 1$, because on ios 11 purchases in cydia isn't supported yet. You can also purchase on another device running iOS10 or lower and link your account.

Also this version has the bonus of a modern-style blurred folder with the iOS 6 shape, Mavericks-style folder, and even a folder styled like iOS 4.0 beta 1!

Give ClassicFolders a try if you have tired of having full screen folders, you can configure options from settings app.

If you'd like to use Classic Folders2, then you can download the tweak for free from Cydia's BigBoss repository. Citing the Cydia description, it works only on iOS iOS 8 - iOS11 jailbroken iPhones.
