### What should this feature add?

For now, "Shift + Left Mouse" dragging supports only multi nodes selection.
I hope this method also support multi lines connector selection. I know there is an exist method "Ctrl + Left Click" to multi select one by one. But marquee dragging selection should help select them faster.
