[Xposed Framework Modules] _jis_:
Can you tell me why you need it when we have in GB already implemented much better invisible Statusbar Brightness Control which take zero real estate of your screen?

For example I have Samsung Galaxy Note 2 which have the brightness slider on notification panel, but I switched it off because I use aforementioned GB's Statusbar Brightness Control and I use it on my Nexus 7 and all my other devices too.

I cannot confirm this. Contrary to your experience I am using both modules XGELS 2.1.1 and GB KK 3.4.6 together without any problem and I am using GELS's Lock Desktop Tile with GB's QuickSettings too. See the attached snapshots:

Here is a list of my installed modules. Notice that xposed log is completely error free:
