We’ve introduced the jira:dashboardGadget Forge module as part of the Early Access Program (EAP). With this module, you build dashboard gadgets with UI Kit using Forge. Custom UI support is planned.
Thanks for the information about the Jira Dashboard Gadgets availability in Forge. What about the option to create Jira Custom Reports?. Do you have any plans to add such module in Forge?, you know, similar to the jiraReports that exists for Atlassian Connect Apps.
