Custom views

Hi,

I am unhappy with the different views which are configured.
I need a mix betwwen the tree view and the compact view.

In fact, the fields in the compact view are OK but I need to see the sub tasks with a space at the beginning of the line, like in the tree view. And I can't select all the fields I need in the tree view, some of them are grayed

Is there a way to setup it like that ?

thanks for your help
Fabien
