Visual Scripting Language is a part of Godot Engine that is fairly underdeveloped. But it still is a really powerful system which just needs to be properly improved for it to reach maturity.
The idea is to add UI and UX changes to Visual Script Language that make it much less intimidating and allows for a much friendlier interface and has a Simplified API rather than being a GDScript with Nodes kind of a setup.
Some ideas for improvement would be unifying the scripting graph, improve node quality and UI/UX changes to support the new features. Further, plans would be to ensure less breaking issues/bugs, and improving overall usability.
An extended goal would be to work on the Group Nodes(VisualScript based CustomNodes) to allow for increased and simplified modularity.
