Glad I could help! A few other tips about Google Photos:
1. The main Photos screen for the app will show you all of your photos, both in the cloud and on your phone.
2. If you tap the Menu button and then Device Folders, this will limit the display to locally saved photos (and break it down into the separate directories that they're stored in).
3. If you want to remove a photo from the cloud and from everywhere else, go to the main Photos screen, select the photo, and tap the garbage can icon.
4. If you only want to remove the photo from local storage (and keep it in the cloud), select the photo, tap the Menu button, and then Delete Device Copy.
5. You can also do a mass deletion of locally saved photos that have already been backed up to your Google Photos cloud. Tap the Menu button, then Free Up Space.
6. If you moved a photo to the Trash and want it back, tap Menu>Trash, select the photo (if it's still there), then Restore it. (This can't be done for device copies that were deleted, though.)
