With Eclipse Scout 22.0, the user interface has been completely reworked. The goal was to modernize it and improve the usability without changing basic user interactions. Modern design principles have been applied for a fresh look, an improved user guidance and increased readability. Various widgets have been beautified like date field, smart field, table and many more. Additionally, some widgets have got new features, like the ability to filter the table rows, tree nodes or grid tiles as you type.
