When coding iLogic you often need to check, add, rename or checkmark "key" or "export" in the parameter window.
In order to do this you need to close your iLogic window you are working in, open the parameter window, do whatever you need to do in the parameterwindow, close it, and open your iLogic window again.
Since many engineers have two monitors or are using an ultrawide, you can easilly have both windows open at the same time (if that would be possible).
It would be much more efficient if both windows would be open and usable at the same time.
