Simple task? i don't know, but....
-Take the ancient modifier list and convert it to a node-based workflow, while redesigning the GUI to accommodate this change.
And i'm not talking about complex low level control like MCG nodes, but a higher level control with a modern node-based layout, that should be visually appealing and easier to explore, use and assign/connect modifiers, than the current stack list of operations, which can get cluttered quite easily...
Thanks,
