Hi,
Vector-Wiggle node has list option but Number-Wiggle and Rotation-Wiggle nodes don't have list option, why?

This is just not yet implemented... I forgot it before the release tbh.
2 workarounds are: use vector wiggle convert it to eulers; use a loop
OK. Yes, I'm using the loop for the Rotation-Wiggle list.
Another query is:- In a group node, is there a way that I can make a "New Input" connection in between the previous exiting connections (see the attached image). Because for a large number of inputs (say ~100), it takes a lot of time to move a particular newly created connection from bottom to top.
Is it possible to just drag them up or down in the property window (Ctrl+N)?
Thank You :)

unfortunately that is not possible, sry.
Currently there is no better way than to move the socket up manually..
OK. Thanks, Jacques :)
