Love the product, but can we show next actions by group?

I love the product, it's the best GTD app I have found so far. But can the Next Action list be altered?

Firstly I know I can change the order of items in my projects, so I have sorted some vague prioritization to the project list on the left of the screen - but the Next actions ignores this and just shows in the alphabetical order. Can this be altered to list next actions according to the user-chosen project list order?

Secondly, could we have a dropdown at the top of the Next Actions where you can choose a group and only see next actions in that groups projects? This would help to clarify my thinking when I want to focus on different groups.

I know I could use Contexts but as that just lists all actions it can feel overwhelming, rather than next actions in projects with the chosen context.
