Please make able to manualy change relation-lines join ponts.
Look at that image - a have no way to make it look better.
I try move entity card up/down. Something was changed, but it still looks bad.
And I just waste my time with that attempts to make my scheme look better.
Have a look for that case please
Entity card has point to join relation-lines. User can drag-n-drop line between points.
I don't say that i need drag-n-drop there. Just the way to work with it.
Now i have to move entity cards until all relation-lines makes full-visibility.
Please make something with it!
