You can set the order of the icons displayed in the QSlide apps bar, as well as which icons are displayed.
Open the Notifications panel, then tap the Edit icon on the right side of the QSlide apps bar.
Drag one of the icon handles at the right side of the screen to move its icon to another position in the QSlide apps bar.
Tap More in the upper right corner of the screen to view the available QSlide apps. Checkmark the ones you want to display and remove the checkmark for the ones you want to remove.
Changing the checkmarks automatically reorganizes the icons. When a removed icon is reactivated, it’s placed at the bottom of the available list.
Tap (or press) the Back Key to return to the Notifications panel.
