A fantasy of mine is to develop a fork of Unity but with an editor interface exactly like Flash, that transpiles Actionscript code to Unity's C#, or maybe a subset of typescript would be a better compromise given it's popularity (either by transpiling or by using node/deno bindings to Unity's Api), to truly make unity games as easy to make as flash games used to be, and with the option to export the project to real Unity in case you need to do something more advanced.
Reminds me of https://discussions.unity.com/t/uniswf-flash-to-unity/481812 which was made by an acquaintance of mine. In this case you used the Flash editor but the SWF ran in the Unity runtime.
How about Godot? You can actually fork that since its open-source.
That's true but what mattigames is describing is so far afield of what Godot actually does that one might as well just start from scratch.
Also, I'd be careful making something with a UI that was exactly like an Adobe product, and that essentially matched its function, that UI may be under patent. This is why GIMP can't exactly copy Photoshop's UI.
