Nodes like +, Group oder Switch can have multiple input pins, which can be extended with Ctrl +/-, which is awesome. Often I find myself in a situation, when I want to insert a new input at the beginning of the node. In this case it would be handy to use a shortcut like Ctrl Shift +/- to create a new input on the very left.
Or… or even additionally… re-arrangable input pins via drag & drop in a node inspector… 🤤
