Copy and paste nodes between Godot projects

[SillyBilly10]

Sometimes I want to copy a node I have from an older project because I think It would be perfectly suitable for the project I'm currently working on, but I find out that you can't just copy and paste between projects and you gotta do it manually

This would be very complicated to implement, first of all the way the data would be transferred would be a lot of work and complicated, unless we make the different Godot instances communicate with each other you'd need to somehow store all this data on the clipboard, which is complicated, for example generally the clipboard contains simple data most of the time (if you copy a file in the file manager it doesn't actually just put the file data in the clipboard, it just handles it when you paste it)

And we'd assume here that simple cases would be handled directly, like copying a node with a script attached, or a simple resource like a gradient file

But also how would you handle these situations:

• A script that extends some other custom type, for example Foo which extends Bar, would it also copy this type if it doesn't already exist in the target project? What if it does exist but is a completely different type?
• Other dependencies, like preload resources in scripts?
• Imported resources, how would it handle a node being copied that uses a mesh imported from a file at player/assets/mesh.glb? Would it copy that mesh and the mesh.glb.import file? Where would it put it?
