This feature aim to add a default short hand for looking up wallpaper, right now we have 6 options in the image size filter: All, Small, Medium, Large, Extra Large or a user defined range. What would be nice is 1 more choice like Current Screen or Wallpaper or an other implementation of it maybe a bit more ux focus
Have a extra option kagi.com/images in the filters section in the Size drop down saying something like Wallpaper.
When selected the search would adapt to the current screen size
exemple:
https://kagi.com/images?q=nature&size=wallpaper
Then using this query it can get the values in window.screen.height; and window.screen.width; to get the screen size
