Android's Google+ app is seeing a big update today that adds in a few new features, all focused on photo editing. It's a gradual update that will slowly roll out to devices over the next week or so.
One of the new features is a non-destructive editing mode, which now lets users continue editing photos on a device other than the original device that started the editing. A full resolution can be backed up on a desktop, touched up on a tablet, then finished up on a smartphone, and all of the changes can be completely reverted at any time. Before now, if you began editing a photo on a phone, you wouldn't be able to get the original photo back if you finished editing the photo on a different device like a laptop or tablet. On top of the editing feature is a whole new set of filters and creative tools that borrow heavily from Snapseed.
Viewing photos is also getting improvements, including an “All” view mode that lets you see literally every one of your photos, regardless of where it was backed up from. Currently, extremely large libraries won't show all photos just yet, but the G+ team is working on getting those functional. There's also a scrollbar in this mode that lets users quickly go forward or backwards to find specific photos.
If you use Google+ to manage your photos, this update definitely looks like it's going to be helpful for you. Keep an eye out for your app updates, this one should be showing up over the next few days.
