Canvas Functionality

I would love to see more functionality in the canvas feature. Specifically snap to grid and the ability to link cards without popping in a pre-generated outline. Also, perhaps card stacks that you can open and close, like, have a card titled Act I, with the scene cards for Act I connected, and you close it and it looks like a stack of index cards. That way it won't be so cluttered when you're working on a different part of the project.
