Project Context View
Work Time Tracking Calendar for Jira can be launched from a project context.
As of the version v 7.2.x, a calendar that is launched in a project context view shows the events no matter the source configuration. Meaning a calendar that is open in a project context view will show all calendar events, including the ones that are configured for a different project or no project at all.
You can create new calendars or edit existing ones without leaving the project context. The main buttons are accessible, assuming you have the required permissions.
Note that when it comes to a source creation and configuration, in a project context view, the given project is automatically populated to the source configuration.
