Before updating my phone from 4.4.4 to 5.1.1, I relied on the Screen Filter Xposed Module to dim my screen so my eyes wouldn't be blinded at night. After the update and after looking through ever new little menu and option, I found that the Colour Calibration sliders under the LiveDisplay settings essentially would do what I was using the Screen Filter module for.
Now, it isn't too much of an inconvenience, but it is a bit of an annoyance to have to navigate to that menu whenever I need to dim the screen. The closest I've gotten to making a "shortcut" is by placing the LiveDisplay tile in the app drawer there so I can launch the settings after long-pressing the tile.
My question is this: is there a way to make a widget or shortcut like the one used in the Screen Filter module? In the module, one could add a slider at the top of the notification drawer to quickly and easily dim the screen. Can this be replicated without having to install that module?
Thanks in advance for all your input.
