This would be a 5 if "Compare by page title instead of or in addition to the URL" worked, but it doesn't.
It only compares all titles and ignores the URLs. So all copilot tabs deleted even though they are different topics and urls.
That is "Compare ONLY title".
It should compare URL AND title, to exclude the same URL with different titles (re-named tabs), so the renamed tabs can be manually selected in a second run after bulk delete, to keep them.

I nearly lost hundreds of renamed tabs because of misleading wording and bad code. And can't use bulk delete at all.

Also, feature requests :)

1. ignore query- can this exclude anything after the URL appended by & or ? (youtube list and timestamps, trackers etc) - it seems to exclude only Google search parameters which of course we do not want to ignore?

2. Is it possible to have the full titles accessible in the list, either a horizontal scrollbar, or tooltips of title and URL like FF bookmarks toolbar, or selectable overflow text (like in windows explorer file properties path box)? Often retitled tabs are only different at the end.
