May 1, 2026May 2026: Delivered a UI enhancement in eclipse-sirius/sirius-web to improve diagram readability by introducing an ellipsis indicator when multiple decorators occupy the same diagram position. This directly addresses user visibility concerns (issue #6497) without changing APIs or data models. Implemented via a focused commit and signed off by Gwendal Daniel. The change reduces visual clutter, enhances decision-making during diagram analysis, and improves overall usability for complex diagrams.
