Read the whole OP! Be respectful to each other and don't ask for ETAs, it's considered as being rude!

AOSP Extended is an AOSP based ROM which provides stock UI/UX experience with useful customizations. Being based on AOSP it provides a smooth experience. We have added useful customizations from various other open-source projects and have tried to keep our things simple. A ROM by a user, for a user. #BeExtended
