When what I type is an exact (or exact-prefix) match for a bookmark's title, that bookmark should be the top suggestion — above frecency-ranked history and search suggestions — so I can just press Enter.
Example: I have a bookmark titled YT → https://www.youtube.com. Typing YT should make YouTube the #1 result and autofill it, every time, without me having to assign a separate keyword.
Today: Bookmark autofill is frecency-ranked, so a low-frecency but exact-titled bookmark often loses the top slot to history or suggested sites. The bookmark-keyword feature solves this but requires per-bookmark manual setup, which most users never discover.
Request: Treat an exact/prefix title match on a bookmark as a strong ranking signal that promotes it to the top heuristic result automatically — the same convenience keywords give, but without manual configuration. Optionally gate it behind a pref (e.g. browser.urlbar.suggest.bookmarkExactMatchFirst) for those who prefer current behavior.
