Currently I can connect two Nodes by clicking on the output port of one Node and dragging a line to another Node's input port.
I would like to be able to do the reverse as well: clicking on the input port of one Node and dragging a line to another Node's output port.
Should be trivial, right? And so useful in cases where you think in terms of requirements and goals rather than procedure. ;)
Btw: In case you have a publically accessible bugtracker, I couldn't find it.
