This patch adds a new 'AddOutputSocket' operator to 'Node Wrangler', which allows to automatically generate new output slots for 'file nodes' based on the nodes in selection as well connecting them properly:
I also added a new 'Create File Output Sockets' menu entry for 'Lazy Connect' in case the type of the actual 'taget node' is 'OUTPUT_FILE' so users can add the slots node by node:
What do you think?
Cheers,
Christian
