You can set a search engine from a short predefined list. If your preferred engine is Kagi or Brave Search or a myriad of others, you have to resort to trickery or extensions.
Yeah I guess anything is possible but it takes effort
How much easier can it get than the current dropdown allowing you to choose a search engine?
The current dropdown actually allowing you to choose any search engine (and add search options to any of them as well)
It’s a single click on the search icon in the omnibar. Can’t get easier than that.
