An update to Nokia's extras+info and display+touch Settings modules apps reorganises the screen configuration options in the Settings app for devices running Windows Phone 8 GDR2, making them more accessible, and preparing the modules for future updates. 

The settings, which were previously grouped under one display+touch module, are now broken into three separate modules: display (sunlight readability enhancement, battery saving, and colour profile settings), glance (always-on clock and related settings), and touch (screen sensitivity and double tap to wake settings). 

Each of the modules in the Settings app has a brief description below it's name. The description for touch is "sensitivity, wake up and Windows keys". The last element of this description is currently not present within the touch module, but likely refers to new forthcoming functionality (doing something when the Windows keys are pressed).

Aside from the reorganisation of the settings into separate modules, there are also some changes to the glance module. An additional slide on/off control labelled "Clock and notifications" has been added. Currently, this effectively duplicate the "Off" option in the "Glance Screen" drop down setting, but would make sense if Nokia plans to add new functionality to glance (e.g. display something else, but not clock).

The notifications referred to in the "Clock and notifications" option currently encompass battery life, vibration, and silence, but adding to these is one of those most obvious possible future updates for glance. 

The timing for the potential arrival of any new functionality is not known. However, the first hints of new, display related, functionality in GDR2 was seen a few months before GDR2 was seen publicly for the first time (at the Nokia Lumia 925 launch). The updates and hints described above would fit into a similar timeline for GDR3.
