Hey there 
Not sure if this question has already been posed, but my search attempts didn’t find anything.
Anyway:
My Question:
Is it possible to maybe create a Reverse Input Button? Not on all but i.e. on the Multiply/Add Node or other nodes that have two interchangeable inputs ?
Why I ask is for sheer organisation of the node tree. To reduce crossing Lines… (see Screenshot)
Of course you can always just reconnect them properly but sometimes the lines are far away and it needs a lot of fiddling… just a question for pure “ease of work”
Thanks!
