Only search in the current folder when using type-ahead
When using type-ahead (just starting to type instead of pressing Ctrl+F first) I think it would be better to only search in the current folder, not recursively. That's because this type of "searching" is most commonly used to navigate around.
Currently it's possible to disable recursive search in the settings, but this will also disable it all the time, even when using the search button or Ctrl+F. Maybe the text label "Only search in current folder" under the search input field could also be turned into a checkbox.
