 Each Agent Manager session runs in an isolated git worktree on a separate branch, keeping your main branch clean.
 
+### PR Status Badges
+
+Worktree items in the sidebar display a **PR status badge** when the branch has an associated pull request:
+
+- **Open** — badge indicating the PR is open (its color can also reflect review and check status)
+- **Merged** — purple badge indicating the PR has been merged
+- **Closed** — red badge indicating the PR was closed without merging
+- **Draft** — gray badge indicating the PR is in draft state
+
+The badge appears on the right side of each worktree item and updates automatically via polling. If the worktree's branch doesn't have a PR yet, no badge is shown.

 ### Creating a New Worktree Session
 
 1. Click **New Worktree** or press `Cmd+N` (macOS) / `Ctrl+N` (Windows/Linux) to create a new worktree

 ### Is the context progress graph still available?
 
-The context progress graph will be [added soon](https://github.com/Kilo-Org/kilocode/issues/8210) for users who like to see it.
+Yes — the context progress graph (also known as the task timeline) is now available. It appears at the top of the chat panel and shows:
+
+- **Timeline bars** — colored bars representing session activity (different colors for read, write, tool, error, and text parts)
+- **Context window progress** — a three-segment bar showing used, reserved, and available tokens, with a visual indicator when usage exceeds 50%
+- **Token breakdown** — input, output, cache writes, and cache reads display
+
+You can expand or collapse the graph — your preference is saved in the `kilo-code.new.showTaskTimeline` setting.
 
 ### I like to closely monitor and approve the behavior of the agent. How can I do that better in the new version?
