Better groups

Problem/Motivation

It seems group in display setting does not work correctly. (Header)
When we have for example status - "Open, Closed, Cancelled etc"

And we want to show all projects Open it looks like:

>Open
    >Projekt 1
>Open
    >Projekt 2
>Open
    >Projekt 3

Is it possible to group it so it shows:

>Open
    >Projekt 1
    >Projekt 2
    >Projekt 3

And also now when you click on display settings the group does not work until you order field to the first position, even if you select a different one. So always it takes header from the first row, no matter what is selected in settings.
