Kibana introduced Pinned Filters in version 4.1, allowing users to create filters in one part of the platform and carry them across different applications within Kibana, enhancing data exploration and analysis. This feature, inspired by a user suggestion, enables seamless transition of filters through a simple 1-click operation, where users can pin filters by selecting them and clicking a pin icon, making it easy to identify and manage pinned filters. By using the Actions menu, users can pin multiple filters efficiently, and these pinned filters persist when users switch between applications like Discover and Visualize, allowing them to explore data more effectively by maintaining context across different views.
