It would be both useful and cool to have search suggestions adapt to inputted bangs (with the ability to turn this feature on/off). For example, when searching "hello" on Kagi in the UK, the below are the suggestions.

When searching "hello" on YouTube in the UK, the below are the suggestions.

I would like search suggestions to be aligned with the relevant bang to reduce friction between the two search experiences. Unsure if this is technically feasible or would require disproportionate effort to implement, but it would remove a layer of added effort (if a user is wanting to see what, in this example, YouTube suggests to them). Importantly, this would draw only from default regional bang-specific suggestions — it would not and should not include personalised suggestions for users logged in to YouTube.
So, when a user types in the bang before their search term (not after, given their desired search term would already be inputted then), bang-specific search suggestions should pop up.
