The version there is having issues,
1. That is very much lagging, this one is very smooth
2. No torch working on official rom
hmm i m not sure about official right now, but the one I have installed from this thread, when I install app which controls overall system they dont work outside the app. For example I have installed an app to control the color warmness (making whole screen red F.LUX type software) it worked, but as soon as I go to home screen it changes to color back to normal.
2nd example is "Toucher Pro" It put a small floating touch icon. When I open its configuration I can see that Icon, and i can move that around, but that is not displayed on the home screen in MIUI rom.
