The original command line AI gave me the ability to close tabs. I could tell it a group of tabs to close without having to locate and close them manually, but what I really miss is "close all duplicate tabs".

Being able to close all duplicate tabs, not just the duplicates of a specific tab was a useful feature.

There is a site that I liked to be able to open all the links in the background and then close all the duplicates (it was 30% duplicates) then I reviewed all the unique tabs that remained.

I simply cannot do that anymore. Please bring back this feature, either in the new sidebar AI, or otherwise.
