We are still talking about modding and customization, so of Xposed Framework and this weekend we see as protagonist a module that transforms the appearance of our notification area.
Blurred System UI is a new module that allows us to customize the notification area with theblur effect (blur). Even if it was born recently, it works very well and allows you to set the effect as we prefer. Among the settings we find the blur radius, the color filter and the option to also have the notification background with the same effect. The latter option is enabled by default, but disabling it the appearance of notifications is not nice to see, perhaps due to a graphic bug.
I remember that it is necessary to have the ROOT and Xposed Framework permissions installed in order to activate the modules, which you can find directly from the app through the Download section.
