What I meant for the collision layers are that there are more options on collison layering. There may be many of them, but they are useful on the later run.

Also, the annoying borders are still there, the basic color material are still there (you can use a web browser and a converison site to find the appropriate colors in HSVA), and other stuff. You can make the ropes look better by clicking on the "Clear Texture" button. You can "move" objects to the foreground and background by rolling the scroll wheel on a selected object.

Uhm… Yeah no.
