What about stucking search on top of either of the two, and preserve 2 columns
Discussion
That's where it used to be, but I think it's more important to have the page / feed name in the header so you know what you're browsing (also serves as "return to top" button).
I see. That makes sense.
Just that the 3 panes seem cluttered on smaller screens usually.
I think you might still be able to maintain visual prominence of the 2 columns while having just a distinct search bar floating at the very top of the UI. Maybe similarly like some of the shopping sites. Expanding upon search.
Sur un téléphone portable c'est plus encombrant pourtant j'ai un grand écran de marque sud coréenne je resterai sur mon ordinateur même si je ne voulais point d'apps dessus
