Nodal Interface for Actions Creation
Similar to 3DCC software and video compositing software, I would like to see a nodal interface where we could add different menu items and specific actions into a tree and have them end in an output node, allowing reuse of specific actions and menu items within the tree in a single action.
I'd also recommend there to be a way to group some of the nodes and be reusable/ able to add them into other action node trees as subgroups. That way some very complicated actions could be recycled instead of always being recreated from scratch.
I have been making better use of the action panel lately, and as I go back to them I find I need to recreate elements of them so that I can create new combinations for specific purposes. A node editor interface might be easier to get deeper control of the tools at hand.
