Body (from Message Center)

Introduction

We’re introducing new multitasking enhancements in Microsoft Fabric to help users work more efficiently across complex workflows. These updates improve navigation, context awareness, and workspace management—making the experience smoother, faster, and more intuitive.

When this will happen

Public Preview (Worldwide): Rollout begins early September 2025 and is expected to complete by mid-September 2025.

How this affects your organization

Horizontal tabs for open items: Users can easily switch between notebooks, pipelines, reports, and more, with clear labels showing name, type, and workspace indicators.
Support for multiple open workspaces: Users can open and work across multiple workspaces side-by-side. Color coding and numeric labels help distinguish items by workspace, reducing confusion.
Object Explorer: A structured view that allows users to browse and open items across all currently open workspaces without switching pages.
Raised open item limit: The previous 10-item cap has been increased, allowing users to keep more tabs open and active for uninterrupted multitasking.

These changes apply only to the Fabric experience and do not affect Power BI.
