so when a user decides to insert a plugin that has 2 inserts and 2
outputs in between 2 plugins that have 1 output and 1 input
respectively, what do you propose to do with the signal?

when a user adds a 1 input plugin after a plugin with 2 outputs, what do
you propose to do with the signal?

when a user deletes a 1 in/1out plugin from between a 1out and a 2in
plugin, what do you propose do with the signal?
