[Feature Request]: Improve Group Node UX with Subgraphs

[ronan36880]

Is there an existing issue for this?

• [X] I have searched the existing issues and checked the recent builds/commits

What would your feature do ?

This change would make editing and working with group nodes much easier. This is something that apparently has been discussed a lot in the past, and seeing that the frontend can evolve much faster (and better!) now, I think it would be a good idea to bring it up again.

Proposed workflow

I don't think I would do it justice to propose a workflow for this. Instead, having a read through this issue and through some of the issues brought up in this comment should provide a lot of context on previous discussions on this.
