It would be cool and useful to be able to search in multiple languages via a Kagi Translate integration that performs concurrent searches in languages that the user specifies.
For example, if I am searching for "cheesecake recipes" and want to find examples of authentic German cheesecake recipes, an integrated Kagi Translate would translate "cheesecake recipes" to "Backrezepte für Käsekuchen" (or context-dependent variations of this, as below, since Kagi Translate provides a number of translated options) and search this concurrently.
Those search results would then be displayed in translated form alongside the English results, but the user would have the ability to filter between originally English and originally German results. Titles and snippets could be translated too, as per user preference. The page translation itself would only take place if the user clicks on a German result (and uses the Kagi Translate extension to then translate it).
This example is fairly simple and innocuous, but a feature-set like this would be somewhat revolutionary — allowing users to easily search in multiple languages and tapping into a wealth of previously inaccessible content (and being able to do this outwith an LLM interface). This is especially powerful for academic/scholarly use-cases where some content is just inaccessible/unsearchable due to language barriers.
I would imagine that this feature, UI-wise, would sit alongside the current regional selection.
It would be something like: Search in: [drop-down search menu of languages] or Show results in: [drop-down search menu of languages]
In addition to this, users could have universal search settings wherein they can set their account-wide search language preferences to always search in multiple languages — very useful for bilingual/multilingual users like myself. These could also be activated by a bang, much like regional searches can be activated at present, like !de
