I saw a game creation tool on indiegogo that lets you do game creation in a browser. The interface was way behind Construct very beta. But one thing that was really awesome was built in pathing.
It allows you to draw directly on the layout, a path for enemies/players to follow. It seemed to be very flexible where if a sprite hits a path, it has behaviors built in. It looks a lot like when you draw bounding polygons in Construct.

My suggestion is to pull in work from third party plugins, and eventually add some sort of ability to follow a path and do behaviors on that. Maybe triggers if you hit a path etc.
