 # gh-threads

 A read-only terminal UI for people receiving GitHub pull-request reviews. It
-shows open PRs, review threads with highlighted diff hunks and comment authors,
-reviewer/assignee state, and the latest commit's check rollup. Resolved threads
-start folded. GitHub suggestion blocks are shown as syntax-highlighted
-remove/add previews. Comments render GitHub Flavored Markdown, including quoted
-replies, inline and fenced code, lists and tasks, links, tables, emphasis,
-strikethrough, emoji, and GitHub alerts. The current PR is refreshed in the
-background.

 Command-line flags override the configuration. `GH_REPO` overrides the
 configured repository when `--repo` is not provided. The corresponding flags
 include `--config`, `--theme`, `--poll`, `--fold-resolved`,
-`--thread-list-width`, `--path-scroll`, and `--path-scroll-interval`. Boolean
-settings can be disabled explicitly, for example `--path-scroll=false`.
+`--thread-list-width`, `--dashboard-mode`, `--path-scroll`, and
+`--path-scroll-interval`. Boolean settings can be disabled explicitly, for
+example `--path-scroll=false`.
+
+With the default `dashboard_mode = "hotkey"`, opening a PR goes directly to its
+review threads and `d` opens the dashboard only when requested. Set
+`dashboard_mode = "intermediate"` to follow picker → dashboard → review
+threads instead.
