I can't understand what is the "top view". Is this mean "Home Screen/Launcher" of webOS OSE? If yes, you can refer this topic : [Home screen customisation](https://forum.webosose.org/t/home-screen-customisation/1144)

i mean... a screen that users can see regardless of other apps, activities..etc.  
for example, when i change brightness setting, i can always see brighter or dimmer top view screen while using that device.  
i would like to customize that screen's filter.

@haileykim  
I don't know exactly, because I'm not a GURU of the luna-surfacemanager which is responsible for graphics management in webOS platform. But, I think this topic ([https://www.webosose.org/docs/guides/core-topics/graphics-input/graphics-input-overview/](https://www.webosose.org/docs/guides/core-topics/graphics-input/graphics-input-overview/)) can help you.

Also, you can find the source code on github : [https://github.com/webosose/luna-surfacemanager](https://github.com/webosose/luna-surfacemanager)
