My dreams bring up one more idea what I'd be happy to see in small GG. That is additional stab section (small one) which will keep voltage at 3.7v. It should be something available on the market I guess. The one is used for Riva for example. As I know this things a pretty small and the question is more how to add it to GG in the same style with possibility to remove in case it broke to vape pure batt.
