I have 5 ideas.

1. A competition for new assets. Each person will be able to submit assets, but you need a certain amount of trophys first. With deadline too 😀
2. Animation tips, as little windows that are movable with 3 pictures for tips atleast.
3. A welcome animation and sign up that is sent to the website automatically when you first get the app.
4. Even folders for projects and stick figures + opacity slider for nodes, with choice for rbga or hex color codes.
5. More customization on the right corner.
