How to respect the page hierarchy when I create a menu?

Hello,

Creating a menu with WordPress is a pain…

The box listing the pages is ridiculously small and when we add pages, it does not respect the hierarchy we created previously.

If I create theses pages:

– Our society
— What we do
— Our history
— Blablabla

You can see that What we do/Our history/Blablabla are children of Our society.

Currently, when we add theses 4 pages, they are added to the same level:

– Our society
– What we do
– Our history
– Blablabla

We have to waste our time with drag and drop to do this:

– Our society
— What we do
— Our history
— Blablabla

This is a small example, but when you have bigger menus or many sites to create/manage for your clients, this a real waste of time.

It sad, we are in 2016 and the creation of menus has still not been optimized for years.

So… is there a good plugin (free or not) do to this BASIC thing?

Thanks a lot
