Gallery app documentation doesn't correspond to real life.

[piiskop]

1. There's no such app as Gallery. It's called Photos.
2. One can't find any buttons for gallery in the top right corner but only in the list of applications in the top bar.
3. There are no sorting options shown.

Gallery docs are gone. Closing.

Use #1889 to track replacing with Photos docs (to be developed).
