Is there an existing issue for this?

• I have searched the existing issues

Summary

"Gantt Chart", "Kanban" & "Calendar" Layouts are not available on "All Issues/Global View".
I think these are critical layouts for the "All Issues" panel that adding can reduce the everyday pain points of project managers.

It's also been requested before in different comments like here.

Why should this be worked on?

These are some important examples of why the mentioned views are so critical for project managers.

‌

Gantt Chart in Global View:

As a Manager, I need to see all issues from all Projects in the Gantt Chart Layout so that I can:

Recognize the Important deadlines between all projects

Kanban in Global View:

As a Manager, I need to see all issues from all Projects in the Kanban Layout and Grouped by Assignee so that I can:

Manage the Workload of all employees (Workspace members) in one view, without having to check every single project. [Display settings: Group by Assignee]

Calendar in Global View:

As a Manager, I need to see all issues from all Projects in the Calendar Layout so that I can:

Recognize the Busy and Quiet working Days of the Team that Help me plan better for the meetings, events, etc.
