I never click on video results in the main search feed. I would the ability to omit video search results in settings or via a hamburger menu in the video result widget itself.
I am happy to use the videos tab when searching for videos but it takes up unnecessary space (especially on mobile).
In settings, a toggle for each search result type widget — videos, quick results, images, etc. — with the ability to toggle these off. An off toggled search result type would no longer appear in the main feed (no affect in something like the videos tab).
