On mobile (Android; can't test iOS), when you search for something, then click the menu icon (the three lines at the top right) and try to switch to Kagi News or Kagi Translate, it opens as if you clicked a search result, not directly in the app (like it does with Assistant, Small Web, etc.).
I expected that it would open "directly" in the app, like it does with, for example, Assistant, and not in a "tab" like a search result.
