Having always used handcent for pop up notifications, I find this new messenger very good.They killed off that redundancy but introduced a new one with the SMS messenger app. Apparently it's only installed by default on the Nexus 6 though so we were spared.
I still have gallery on my PC where I upload all my botanical identification photos (many hundreds). On my Nexus 5 they are set to view offline if need be. What replaces Gallery? And will that require a change on my desktop?Apparently it is.
