Minimal Ultrawide Theme for Twitter / X: Full-Screen Multi-Column Feed

Wide, full-screen layout for X (Twitter) on big monitors. Multi-column masonry, horizontal or vertical scroll, hides promoted posts.

X (Twitter) gives your timeline one thin column and leaves the rest of a wide monitor empty. On a 3440 x 1440 screen, about 64% of it shows nothing. X Ultrawide puts your whole screen to work. WHAT YOU GET Horizontal masonry: posts pack into full-height columns that scroll sideways, with a scrollbar along the bottom. Vertical masonry: prefer scrolling down? Switch to a classic multi-column masonry in one click. Cleaner layout: an icon-only menu, search in the top bar, and the composer and trends as the first cards. Ad blocker: hides promoted and boosted posts, which you can turn off any time. Adjustable card width: from 320 to 900 px. Light and dark themes: it follows your X theme. Remembers your place: open a post and come back to where you were. ONLY WHERE YOU WANT IT It changes the Home timeline and nothing else. Profiles, posts, search and settings look exactly as X renders them. PRIVATE No accounts, no tracking, no analytics, and nothing leaves your browser. Your settings sync through your own Chrome account.
