Here is my Smart Merge.
In addition to the option to link selected components, it also provides a Graft all inputs and a hide all wires.
And it also integrates a tree branch simplifying similar to Suirify - in other words, it works well for items and lists, while auto-simplifying trees.
If GH2 could somehow implement these options, I would be delighted !
Edit : added Smart Entwine & Smart Trim Tree
