Ability to hide elements and better Auto-Align
For me it is very important to hide elements. In my case I use a State Chart Diagram and there are many overlapping transitions. The description of these Elements will make it very confusing.
Also the auto-align ability is not that good. It squeezes the Diagram too much.
I would like the option to rescale the container smaler than the longest line. The whole line could be shown on mouseover( after 1s )
