@leocg That wasn't my original subject for this bug report. And if you look at expected behavior, you'll see that it isn't my main concern.

My concern is that the sidebar AI looses functionality that existed in the command line AI.

I could tell the command line AI to "close all duplicate tabs" and it would remove all duplicates of any tab, not just the duplicates of a single tab. That was honestly useful because I could open any link that looked interesting on a page (many of which were repeats) and then tell it to close all duplicates.

The changed subject line should be fixed.

Aria helped me out by creating this bug report. Hopefully we got everything right.

I am experiencing a significant usability issue with Opera AI (Aria AI) related to the Sidebar AI and Command Line AI modes. Specifically:

When the Sidebar AI is enabled, pressing Ctrl + / opens the Sidebar instead of the Command Line interface.
The Command Line AI allows powerful tab management commands (such as closing duplicate tabs) that are currently inaccessible through the Sidebar AI.
Disabling the Sidebar AI restores the Command Line functionality and shortcut, but requires a full browser restart to switch modes.
Switching back to Sidebar AI also requires a restart, making toggling between these modes burdensome and impractical.
This behavior severely limits the seamless use of Opera AI features and impacts productivity.

Steps to Reproduce:

Enable Sidebar AI in Opera.
Press Ctrl + / to open the Command Line.
Observe that the Sidebar opens instead of the Command Line.
Disable Sidebar AI.
Restart Opera.
Press Ctrl + / and observe that the Command Line opens as expected.
Enable Sidebar AI again.
Restart Opera.
Press Ctrl + / and observe the Sidebar opens again.

Expected Behavior:

The Sidebar AI should fully handle all the functionality currently available only through the Command Line AI, including advanced tab management commands.
Users should be able to access all Opera AI features seamlessly through the Sidebar AI without needing to switch modes or restart the browser.

Impact:
This issue disrupts workflow by forcing restarts to switch AI modes and limits the usability of powerful tab management commands that are not yet integrated into the Sidebar AI.
Environment:

Opera version: 126.0.5750.18
Operating System: Windows 11
