Tabs from all windows

Description

I really would like an option to have all tabs from all windows visible in the sidebar.

I would also like a similar function. Extended search function similar to tabby. Currently using tabby to search/filter all tabs of all windows. But tabby is not really performant. Maybe tabby has no cache or only creates it's tab list on opening of the window.

I'd like this as well. Sometimes I lose track of a tab that's in another window on a separate workspace or virtual desktop. With a feature like this I could track that tab down, and perhaps move it to a more appropriate window.
