-**Why gh doesn't have it:** `gh` outputs flat text only. Extension `ghdash` (very popular) proves massive demand for a rich terminal UI, but it's external and limited.
+**Why gh doesn't have it:** `gh` is command-first and outputs flat text. External tools like `ghdash` prove demand for rich terminal dashboards, but they cover only part of the GitHub workflow. `ghg` can make its whole feature set browsable, actionable, and keyboard-driven from one terminal-native interface.
 
 **Commands:**
 
-- `ghg tui` — launch full screen terminal UI
-- Browse PRs/issues with keyboard navigation (vim bindings)
-- View diffs with syntax highlighting in terminal
-- Inline comment and approve without leaving TUI
-- Filterable, sortable tables with live refresh
-- Split pane view: PR list on left, diff on right
-
-**Value:** A terminal native GitHub dashboard that doesn't break flow. Developers who live in tmux/neovim will never leave the terminal.
+- `ghg tui` — launch the full-screen terminal UI
+- Dashboard home for notifications, mentions, activity, PRs, workflows, repository health, and active profile
+- Command palette for every major `ghg` workflow without memorizing subcommands
+- Keyboard-first navigation with vim-style bindings, tabs, search, filters, and sortable tables
+- Notification and mention triage: open, mark read, mark done, jump to related PR/issue/repo
+- PR and review workspace: list PRs, inspect metadata, open threads, resolve threads, create comments, approve/request changes through existing review flows
+- Repository workspace: inspect, govern, label, retire, and report across configured repository targets
+- Labels workspace: pull, push, prune, compare templates, and preview sync impact
+- Insights workspace: traffic, contributors, commits, frequency, popularity, and participation views
+- Workflow/run workspace: validate workflows, preview generated workflows, debug failed runs, and surface logs/status summaries
+- Profile/config workspace: view active profile, switch profiles, detect local profile, and edit common settings
+- Action details pane with human-readable summaries plus an explicit JSON preview/export path where relevant
+- Lightweight file, comment, and status previews; rich next-generation diff review remains a separate future milestone
+
+**Value:** Turns `ghg` from a set of powerful commands into a terminal-native GitHub cockpit. Users can discover and run the full product surface from one keyboard-driven UI while preserving scriptable CLI commands and explicit `--json` output.
