The page operations in general have been a mess for years. Why create a special tool to 'organize pages' when the functions could easily be added to the left page thumbnail views in a more intuitive way.

I have seen over two dozen people try to modify pages unsuccessfully the exact same ways using the page thumbnails section. This means there are at least a few and likely more intuitive designs that can be implemented. A bit of user research can help improve the UI dramatically. Apparently, little to none was done.

Establishing editing functions around standard UI interactions and existing layout can be achieved without having to transition to a completely different view. Please, hire some trained UX designers (not graphic designers, or programmers). I beg you.
