Well, you wouldn't need the chat function, so that might save some space. Perhaps there's a way to automatically share the diagram when someone is added to the Wave? ( I make these suggestions, btw, as a user, not a programmer.) That would eliminate the space for the share drop down... There wouldn't probably be scrolling within the wave, especially if it is left at the default view. ... Yes, you're right, probably be pretty tight on space. I've used NapkinGadget, but it requires drawing freehand, which produces, well, poor results. Good luck!

I'd like to be able to create and group-edit the diagrams, while leveraging Wave's other collaboration methods.
