[Feature Request] Unify Expert Workspaces: Add 'Notebook' and 'AI Studio' as Primary Top Tabs

:pushpin: Problem Statement

The current desktop/web application structure creates massive context-switching friction. While Gemini Spark occupies a highly discoverable primary top-tab layout (Conversa | Spark), Gemini Notebook is minimized as a standard list item at the bottom of the sidebar. Furthermore, Google AI Studio remains entirely isolated as an external web tab.

Juggling between general conversation, background agents, source-grounded research, and raw API prototyping requires constant tab-hopping and manual file re-uploads.


:light_bulb: The Solution: A Unified Top-Navigation Matrix

I propose standardizing the primary top navigation into a modular, four-tab expert workspace framework:

Tab Name Current UI Location Proposed Function in Unified Framework
Conversa Top Tab Standard multi-turn general conversational assistant.
Spark Top Tab Proactive background agent workflows and automation.
Notebook Bottom Sidebar Deep, source-grounded research (PDFs, notes, audio overviews).
AI Studio External URL Raw API prototyping, system instructions, and temperature tuning.

Visual Concept: The top bar should dynamically shift the workspace layout from [ Conversa | Spark ] to:
[ Conversa | Spark | Notebook | AI Studio ]


:rocket: Business & Developer Impact

  1. Zero UI Friction: Eliminates tab fatigue by allowing developers to fluidly toggle modes within a singular native window.
  2. Data Continuity: Allows seamless asset sharing—e.g., testing an API prompt in AI Studio, running a background agent on it in Spark, and saving the output sources directly to a Notebook.
  3. Ecosystem Locking: Unifies Google’s fragmented power-user tools into a single, cohesive powerhouse workspace that rivals any desktop IDE or AI assistant wrapper.
