Filtered Group Inputs for Node Editors

I am really glad with the last UI improvements for the Node Editors such as Sub-panels and the grayed-out items! But there is something that bothers me for quite some time.

When the user creates a Node Group for Shader or GeoNodes some times it can get a really massive list. The panels help a lot on the interface outside the node groups but for the internal interface of the node it can get really complicated to deal with it, specially when you want to drag a new socket for the Group Input Node.

Of course we can hide it with Ctrl + H (manual work) but even though it we need to unhide it to plug new sockets. (In this case I have repeated the Panel name in the sockets for find it faster when looking in the Node or the Socket List as the panel automatically hides the matching name for the parent panel for the socket)

My Idea:

(I have made the exact same post yesterday but it is in an endless 'processing' status and don't even appears in 'ideas' section in my profile, if it get doubled I'll delete some of the two!)
