Kagi's current documentation is generally pretty solid but nothing's ever perfect. I've occasionally read some of the docs and thought "they should have a section elaborating on this" or "this needs more detail" or "this is confusingly-worded". Currently, it doesn't seem like any of the existing kagifeedback categories or subcategories accurately capture this feedback.
Similarly, any feedback on "Account Settings" or "Kagi meta pages" (basically, any Kagi pages that aren't specific to any one product) doesn't fall under any existing feedback category. This would probably have subcategories for "Settings", "Billing", "Security", etc. Currently, some of the most popular suggestions on here are just generically tagged as "Desktop, Mobile, Suggestions" but would fall under these existing categories (e.g. add PassKeys or 2FA).
I'm not sure what needs elaboration in terms of "how will the user use this proposed feature" other than "adding categories for subjects that are currently 'uncategorizable' makes it easier for users to see if their feedback already exists before making a new ticket".
