This plugin allows to insert node into existing wire or wires. Works similarly to one of the quick drop shortcuts, but it has some more features.
Some key functionalities:
Inline node into single or multiple wire with a node alignment selection.
It can handle dynamic dispatch and polymorphic terminals
It can inline not only subVIs but anything what inherits from Node class, e.g. structures
The plugin is little buggy (e.g. in some cases it brakes undo sequence) and does not behave always perfectly (e.g. on branched wires), but with a bit of experience and knowledge where not to use it, I find if very useful. Hopefully someone will take this idea and create something more robust.
