It would be great if all of the objects that use a buffer~ (groove~, play~, etc) were capable of text completion by giving a list of all existing buffers. Kind of like when you begin typing into a message box: if there's an object nearby it suggests messages based on what that object accepts.

This would be pretty good, also for things like [coll]. I'm still yet to get Max 6 and this might just push me over the edge.

I'd love this for send, receive and forward as well
