• Open PR in editor (e) — open the selected PR in a configurable editor command (nvim with diffview/octo, code, etc.). Suspends the TUI, runs the command attached to the terminal, and resumes on exit. Configure editorCommand and repoPaths in config.json with gh-dash-style {{...}} substitutions and owner/repo path matching; falls back to $EDITOR/$VISUAL.
• PR workflow runs view (a) — see a pull request's GitHub Actions runs full-screen (a peer of the diff view). Browse the commit's runs, drill into jobs and steps, jump between failures with n/p, and open a step's log or the run in the browser. Backed by gh run list / gh run view.
