View multiple X timelines side by side, like X Pro. Noctra adds a multi-column deck to x.com, so you can watch several timelines at once without leaving the regular site, similar to X Pro's grid view but running entirely inside your browser. What it does: - Adds a "Deck" item to X's left nav - Shows each timeline in its own column: Home (with a For you / Following toggle), lists, notifications, bookmarks, search results, or any profile - Drag a column's header to reorder it, drag the right edge to resize - Uses X's own icons and fonts throughout, so the deck looks like a native part of the site Why install it If you follow more than one feed, list, or search on X, switching tabs constantly gets old. Noctra puts them side by side in one view, backed by real, live X pages (each column is an actual x.com page), so everything behaves exactly like browsing X normally: same login, same interactions, same real-time updates. Privacy Noctra runs entirely on your machine. There is no external server, no analytics, and no extra login beyond your existing X session. It only reads/writes to Chrome's local storage to remember your column layout. Getting started Click the Deck icon in the toolbar or press Alt+Shift+D on x.com. Use the + button to add columns: pick a preset timeline, search a keyword or handle, paste a list or profile URL, or choose from your own X lists.
