Set Agents window as the default main window

Type: Feature Request

I would like to request an option to make the Agents window the default primary window when opening the application/workspace.

Currently, I have to switch to the Agents window manually each time. Setting it as the default would improve workflow efficiency and reduce repetitive steps for users who primarily work with agents.

Expected behavior:

Add a setting to choose the default main window on startup.
Allow selecting Agents as the default.
Persist this preference across sessions.
Why this is useful:
This would streamline daily usage and provide a better experience for users who rely on the Agents view as their main workspace.
