It is good time to make the Construct great again

For the record, we want to do both: an easy-to-use tool for beginners, and also a capable tool to build and publish a full game. So we need both features that help absolute beginners get started (like guided tours), and help advanced users go further (like JavaScript coding).

this is missing an important part:

advanced features for advanced games.

They have the option to use TypeScript instead :)

or they can stick to the basics and rely on JavaScript/TypeScript addons made by others, which is totally okay (but not "advanced")
