When working in AI Studio across multiple sub-accounts, switching to another account currently requires leaving the AI Studio editor with the back arrow, opening the main sub-account switcher in the top-left corner, selecting another sub-account, and opening AI Studio again. Repeating this interrupts the workflow and adds unnecessary navigation.
Please add a sub-account switcher directly in AI Studio's top bar, accessible from a clearly identified account icon or dropdown, both on the project list and inside the editor.
Expected flow:
  1. Open the account switcher without leaving AI Studio.
  2. Search for and select an authorized sub-account.
  3. Land directly on that sub-account's AI Studio home/project list, ready to open a project.
The current sub-account should remain clearly visible. The switcher should respect existing permissions and protect unsaved changes or warn about an operation in progress before switching.
This is a navigation request, not a request to move or clone the current project. The goal is to reduce clicks and preserve the AI Studio working context when managing projects across accounts.
