actionButton - how to display the button in the list view / subpanel list ?

Hello,

actionButton is really a cool feature but few things are missing.

My current expectation is the following one : you can display a button inline on the record view (meaning that, instead having it in the header you can put it on a specifiy position). I want to know if one of you extend it to be abble to put it on a list view or subpanel view.

I am aware that I can add it to the "menu" for the list view. But I want a more efficient layout where my customer can easily run the button from the subpanel view, without having to open the menu (it is for a "todo list" subpanel where the user valid / invalid the record by pushing the rght button).

Many thanks,

Fred
