Compatible with iOS 8, 9, 10 and 11
I have not tested on iPad yet, so i do not know if it worked there. Please bring back to me, thanks.
WhiteFolders is my new tweak that makes your Folders White (when closed) with the choice to change the Custom Background Alpha of the Folders too.
The tweak is born also with four Extras to manage more Folders Options.
1) Enable Adaptive Colors: it enables the Adaptive Colors of the Folders.
2) Enable Inside BG Transparency: it enables the Transparent Background inside the Folders.
3) Speed Up Opening: it speeds up the opening of the Folders.
4) Speed Up Closing: it speeds up the closing of the Folders.
Disable/Enable and respring in Settings after the installation to take effect (a Confirmation Button will appear to respring the Device.)
