Diagrams, Xtext and UX
The document discusses user experience (UX) and how diagram frameworks can introduce quirks that negatively impact UX. It notes that good UX is why people like products and advocates taking back control over UX from frameworks to eliminate quirks. The document promotes FXDiagram as a diagramming solution for the Xtext language development framework that avoids quirks by providing tight integration between the diagram editor and Xtext.
