defining relationships

[Poikilos]

This web app is much faster and easier to use than others! Creating patterns only takes one drag, or a double-click to edit without a separate popup. However, there is a feature I miss: relationships. They could be accomplished using the same direct-manipulation principles:

Put a label along a line

• Add: Double-click the line to add or edit a label on the line
• Remove: Make the field blank to remove the label).

Add an arrow and choose direction

• Add: Drag the line a certain distance, maybe 5% of window width, to make the arrow on the end to which you are dragging.
• Remove: Drag along the line the opposite way to remove the arrow (of course, drag again in that direction to make an arrow on that direction, which would just be repeating the "Add" guesture but in a different direction).

oh same opinion, I think the relationship is pretty important, if that could be implemented, it will be very very nice

I improved the initial post to clarify the suggested steps.
