Draggable connections + canvas configuration

[alex-d-ivan]

1st feature: I couldn't find this feature but it would be nice if the connections could be dragged. Right now if we move a group of nodes the connections start to be messy, so a means to drag them around and position them nicely would be great.

2nd feature that I think would be nice is to configure the sizes of the canvas so the sizes of nodes can be resized automatically based on the size of the canvas. Example: If we need to print a node tree on a paper format, if we can configure the canvas size and then the nodes are resized accordingly the tree would be easy to print.
