Popular cydia tweak quietly keeps track of the applications that you use the most (sorted by time spent in them) and displays them at the top of the App Switcher, replacing iOS 8’s “Recent Contacts” feature.
Tweak features include a blacklist to hide applications and statistics about your most used applications, both of which can be found in the settings. You can also hide section & icon labels.
Popular also includes a “Favorites” section that allows you to select up to 4 of your favorite applications, which will be displayed at the top of the App Switcher. Think of it as a “Quick App Launcher”!
