I did watch the movie. The only interesting thing it has are the types. Besides that, from what I can see in the demo, the interactivity and the options of the GTPlayground/GTInspector is, in my opinion, better. And we just got started :).

Hi Alex! I took a brief look at it and will play with it more tomorrow but it looks great! Especially the RTMultiLine>>block: message makes it is much more flexible for weird use cases (e.g. wanting to have control points while maintaining orthogonality etc). Perhaps we don't even need to add extra option for control points per se and just let it be handled from outside? E.g. something like --------------------------------- v := RTView new. e1 := (RTEllipse new size: 30) elementOn: 'A'. e2 := (RTEllipse new size: 30) elementOn: 'B'. ctrlShape := RTEllipse new size: 10; color: (Color purple alpha: 0.3). ctrls := (ctrlShape elementsOn: (1 to: 2)). v add: e1; add: e2; addAll: ctrls. v elements @ RTDraggable. e := RTEdge from: e1 to: e2. ctrls do: [ :el | el addConnectedEdge: e ]. shape := RTMultiLine new color: Color blue. shape block: [ :fromPoint :toPoint | | points | points := ctrls collect: [ :el | el position ]. points addFirst: fromPoint; addLast: toPoint. points asArray. ]. e + shape. v add: e.
