Hot take: tabs should be banned. Everything should open in a sidebar. Change my mind.

Agreed. Sidebars are the future and everyone's sleeping on them.

Counter-take: vertical tabs in Firefox already do this. The future is now 😌

Only if the sidebar has its own sidebar. Sidebarception.

What it does
🖱ī¸

Hover to load

Hover over any post and replies appear in the sidebar. No clicks required.

đŸ§ĩ

Thread-aware

Replies are grouped into threads so conversations flow naturally.

❤ī¸

Like from sidebar

Like any reply directly from the panel with optimistic UI updates.

↩ī¸

Nested replies

Expand sub-replies inline to go deeper into any thread.

🔒

Your session only

Uses your existing X login. No tokens stored or sent anywhere.

⚡

Smart cache

Already-fetched replies are cached. Re-hovering is instant.

How it works
01

Hover a tweet on X

The extension watches for mouseover events on tweet cards. After a 400ms debounce, it reads the tweet ID from the timestamp link.

02

Fetches replies via X's GraphQL API

Calls TweetDetail using your existing browser session — no extra accounts or API keys.

GET /i/api/graphql/{queryId}/TweetDetail
03

Parses the response into threads

The raw JSON is traversed, deduplicated, and grouped into conversation threads — promoted content skipped.

04

Renders into X's own sidebar

The replies panel is injected into [data-testid="sidebarColumn"] — feels native, not bolted-on.
