It seems like there's a zooming level in the workspace that prevents me from seeing everything. Am i missing anything?

I see it too...seems like you can't keep zooming out, it's as if there's a zoom-out "cap". So for a large network/system (btw, what do you call a system of wired nodes so I get the terminology right?), you have to then start panning to see it all from left to right.

Could you say a little more about what is happening?
