Manual reordering of Inputs/Outputs (and factories)

Having big factories with lots of Items that you add over time the order of things can become quite a mess. So I would like to reorder the Inputs and Outputs, perhaps via drag and drop? Idk sounds like a UI nightmare.

Reordering factories would be nice as well, but these can already be ordered by renaming them as a workaround.
Rather low priority as I only felt the need to do this once in weeks.
