About SideX - Dock Comments Stream & Reader for X
SideX makes X (Twitter) conversations easier to read. Click a post's text or blank area to open its replies in the right-hand column while keeping your timeline in place.
FEATURES
• Docked comments: read replies beside the timeline without opening a separate detail page.
• Long-post reading: automatically open the post's native Show more control when available.
• Conversation threads: expand and collapse reply branches, with configurable reply previews and automatic unfolding of loaded author self-replies.
• Reply loading: see loaded direct replies alongside X's reported total. Main-list automatic loading is on by default and can be disabled. Each branch click loads one page for that branch, with no sibling prefetch or automatic branch pagination. After a manual load, this open conversation stays in click-to-load mode. Folded replies require an explicit reveal action.
• Optional pinning: keep the panel open across outside clicks, Esc and X navigation, with the active post highlighted. Manual close and post switching remain available. Auto-pin is off by default and applies to new panels.
• Reply text: optionally expand long reply text automatically; off by default.
• Reply options: use the inline composer with image attachments, or open X's official reply dialog.
• Text drafts: keep separate drafts per post and reply target, restored on return. Switch posts or close comments freely without a prompt. Drafts last until you refresh the page or close the tab; images are not saved with drafts.
• Photo comments: choose SideX or Official comments beside photos, independently of reply mode. Collapse for a full-width image and expand with reading position and drafts retained.
• Quoted posts: expand and collapse quoted text in place from a three-line preview.
• Quote and share: open X's official quote composer with the original-post card, and use X's official share menu with account and media-specific options, including for replies absent from the native timeline.
• Native interactions: reuse X controls when the matching native post is present. Other comments use your active X session.
• Profile cards: show the actual X hover card when a matching native profile link is available. Otherwise, show a fallback with biography, relationship counts and followers you know.
• Translation choices: use X official translation, choose Google, or use your existing translation extension's selection/page translation.
• Appearance: follows X's theme and supports an adjustable sidebar width.
WHAT'S NEW IN 1.1.27
• Each Load more replies click loads one page only for the selected tweet branch.
• Stops automatic loading of visible branch cursors and background prefetching caused by preview settings.
• Ignores unrelated branch content, visibility changes and cursors included in a branch response.
• Stops automatic loading in this open conversation after a manual click; collapsing does not fetch other posts. Keeps the aligned controls, continued thread line and same-row Load more/Collapse layout.
PRIVACY
SideX runs in your browser and has no SideX relay server or analytics service. It processes the X content you open and uses your current X session for authenticated requests. Text drafts stay temporarily in the current page and are not synced. Replies and selected attachments go to X. If you select Google translation and click Translate, the post text is sent directly to Google. X authentication information is not sent to Google. Other translation extensions follow their own settings and privacy policies.
SHORTCUTS
• Esc: close the current overlay or unpinned comment drawer.
• Pin button: toggle whether outside clicks, Esc and X navigation keep the panel open.
• Drawer close button: close the drawer and keep its text draft.
• Ctrl + Enter: send a reply from the inline composer.
• Ctrl + V: paste an image into a reply.
SideX is independent and is not affiliated with or endorsed by X Corp.
