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 U…
How about Godot? You can actually fork that since its open-source.
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.
