Hi,
After following Martin Hance's session for the academy, one feature request came back to my mind.
This is a "simple" GUI request : having an indicator of input and output values on modifiers.
For it to be clear I did a little prototype of the GUI 
In my mind that could help a lot in situations where you for instance need to chain several modifiers and need to chain them in the right order.
Best,
Mehdi
