Improving CRUD operations on list UI

Thus far, our pages for operations to be done on a collection of things (tasks, pricing groups, permission groups, ...) have this general structure:

If the things getting modified in bulk have "only one thing" about them, we have no tabbed pane, like this:

.

I have been tasked by someone who says that, if he were a user of this app, this design would not be good. However, when I asked him what he would prefer instead, he had no concrete suggestions. I generally agree that this can be revamped, but don't have any hard user-friendly suggestions in mind either.

What say you?

NOTES

  • I see an alternative is to use dialogs to edit things individually (click an item, get an edit button next to it, which, on-click, spawns edit dialog) but that can easily get out of hand
  • list group can overflow the view, and when I go to tame that with max-height, individual list items shrink inwards
  • in mobile mode, the different parts of the page stack on top of one another, for example, this: enter image description here
