Will the Hangouts apps store my SMS messages "in the cloud". Not sure if I want that happening. I text a lot. I also didn't really appreciate it when Google+ took it upon itself to automatically upload my photo library a while back either.
It shouldn't have done that. It asked me if I wanted to do that but I immediately made my gallery offline just for that reason. That, and I really hated the G+ and Picasa albums in my Gallery app. Drove me nuts.
