Apr 1, 2025In April 2025, Deltares/fews-web-oc delivered two high-impact front-end enhancements that streamline content authoring and improve data exploration. The Rich Text Editor enables in-app editing of reports with rich formatting and table support, introducing an editing mode and a save workflow to replace prior display-only capabilities. Thresholds UI enhancements deliver more intuitive alarm navigation by routing selections to the topology spatial time series display, automatic scrolling to bring the selected alarm into view, and targeted UI/theming improvements. These changes reduce time-to-insight for users, improve report accuracy, and strengthen front-end maintainability through code quality improvements and centralized event-driven navigation.
