I got some positive feedback for replacing notmuch-hello search input with a button wich would call `notmuch-search' and read input from minibuffer as usual. This way we do not have to maintain 2 search interfaces and get history, tab completions and other minibuffer features in notmuch-hello search without having to reinvent the wheel.
So I plan to go with this approach and this patch series is obsolete. Regards, Dmitry
