- Process a response and show the result in a pop-up window or toast, or update your dashboard parameters.
Available for the following visualization types: Selector, Table, and Chart (Gravity UI Charts).
Added a dashboard setting to adjust the spacing between charts.
Moved dashboard settings to a right-side panel. To open settings, click at the top while in edit mode. Visual changes apply immediately after saving new settings.
Added the ability to set up the dashboard to display all tabs or selected tabs. Hidden tabs are not visible by default when you open the dashboard, but you see them if you use a link to a hidden tab to open the dashboard.
