Reverse image search is a good feature implemented in Kagi, but it does not help when scanning QR codes. Many establishments and places resort to having to scan QR codes for linking to their websites (menu, shop site, forms, etc).
Kagi reverse image search (mainly mobile) can implement this feature and open the link using Kagi search. Currently users have to resort to other QR scanners (example : Google Lens) for scanning QR codes.
It'll be convenient to take a picture of a QR code and feed it into (reverse image search) using Kagi, to be directed to the link/page represented in the QR code. This will eliminate dependency on 3rd party apps for QR code scanning. Kagi Android/iOS apps will greatly benefit from this, if QR scanning is directly implemented.
