I was just demoing to Antonia. She had similar feedback to us.
Fist, when you want to add more interactions. When we do "get interactions" from the right hand menu, we then need to hit a second "get interactions" again in the advanced list. Then "add interactions"
This would be better if it were reduced to 2 clicks instead of 3. possibly lst click "List interactions" (get interactions is a little generic) (the one in the menu) 2nd click "Add interactions to graph"
