At any rate, I am curious when Google implemented this feature? I don't know if it was in one of the many GMS/Play Store updates, or if it has been there all this time & I just missed it somehow.
Give it a try, if you haven't. Just go into apps, select the "all apps" tab & long press any app that is not installed already. It will put the device into multiple selection mode, where you can select & install multiple applications much easier than selecting individual apps & pressing install for each one. Sure, it's not as easy as using TB or another backup utility, but for those of us that are bumping between KK & Android "L", where most system & data restore apps don't work yet due to context changes, it definitely saves a little time.
I am interested to know if you can do this on any JB or ICS device too. Try it out & let me know.
