I use the Gallery view often, and adding the ability to change how the Gallery view is sorted would be great. i seem to remember gallery view having sorting before the masonry view was added, so I’m not sure if there was some reason it was removed.
Also adding a button on the top bar to enter the regular gallery view from the masonry view, instead on needing to click on an image would be useful, when entering a gallery view with a large amount of images it can take several moments before any image that you can click on to change to the regular gallery view, and there is also already a button to return to masonry view.
