I know your frustration. The new layout of Photo app is a terrible UI/UX design.
First, they assume we would love this new layout with a lot of useless grouping, when the old one is clean, simple and intuitive. They divert from the Apple’s unique design style.
Second, they give a new option to let us rearrange the layout, but that new feature is hard to see. It’s at the bottom of the app, displayed as a sample line. You have to scroll down to the bottom, all the way through their long list of useless grouping as mentioned in #1.
Third, their default layout is totally away from their old system. The frequently used Album and Deleted are put at the bottom by default, instead of being right after the gallery as in the old system. So there is no transitioning for us to know this new App at all. They just dump whatever to the table and demand us to accept it.
I don’t understand who would love it, perhaps only the persons working for this new Photo app.
