A simple project based on concepts discovered by @gtoal here: https://scratch.mit.edu/discuss/post/984862/ This can, without false positives, detect if the user is in the project editor, and it might be able to detect if they remix the project. Press space or click to read the text in the project, or view the (basic) code and costumes required for setup inside. The potential for this is pretty big. Projects could possibly detect all clicks and discover arbitrary user actions...
