First I want to say your doing a great job on this mod. Its incredible how fast it is. As a Gentoo user I also like how your building from source
While I understand you have your own backup and restore apps and settings I'd personally prefer to have Android do it for me. What I am saying is when I wipe my phone I'd rather have Google just auto download all of the apps I previously had and restore the config. Bugless and stock both do this fine but SS doesn't for some reason. I do have the settings checked to do this, it just never happens.
Another issue I am having is with GPS. I don't get great GPS signal in my apartment but I will get in the general area(probably using AGSP). On stock and Bugless it gets it within about 50 meters on maps. In other apps it at least gets my city. When I'm running SS it just says GPS signal not found and dies.
Finally one suggestion Bugless has the Chrome to Phone app. I pulled it from Bugless and installed it on SS and it works great. You might want to consider putting it in your standard build.
Again, great job,
