As my list of quick actions grows, it becomes "less quick" for lack of a better term, and I find myself wanting some level of control over which quick actions are presented. I've been thinking this through, from the perspective of a level of hierarchy or, where I've landed, the idea that you can assign a quick action panel to a specific list or smart-list. Thus if I am in my agenda list, I could have a panel with key people/team names presented, if I were in my shopping list I could have a panel of store names presented (which plays VERY nicely with sort by tag now). If I were on other lists I could have date centric panels presented.
Just a thought.
