Introducing Saved Views in Temporal Web UI

Introduces Saved Views to the Temporal Web UI, enabling users to save and reuse complex workflow queries. This feature includes System Views (e.g., 'All Workflows', 'Running') and Custom Views, which are stored in browser localStorage with a limit of 20 per namespace. The post also details improvements to the filtering experience, including streamlined dropdowns and the ability to copy and edit existing views, as well as sharing views via URL. The new UI is built with Svelte for improved performance.
