- Replace TabView/Tab with Tabs API per Terminal.Gui v2.0.1 (PR #3808) - Set Title on each child view; select via tabs.Value instead of andSelect - Replace SelectedTab?.View lookup with tabs.Value (already View?)
- Add DetailTabBarView: single-row click-to-switch tab strip with arrow/[] navigation hints. Mirrors the existing TopTabBarView pattern. - Replace v2.0.1 Tabs widget with manual mount/unmount of detail content in detailContent. Tabs widget had focus-migration, z-order, and click hit-test issues that didn't converge. - Replace TextView with ColoredOutputView for Extensions and Raw YAML. TextView.OnDrawingContent in v2.0.1 iterates all lines below Viewport.Y (no viewport-bottom break), and View.Viewport setter unconditionally invalidates layout — both visible as per-keystroke scroll lag on long YAML. - Add internal topRow scroll state to ColoredOutputView with a Scroll(delta) method that calls only SetNeedsDraw on this view, bypassing the framework Viewport setter and parent adornment re-invalidation cascade. - Add Editable/ReadOnly visual roles to dark theme so read-only views don't render as light-gray-on-dark.
Render a 24-bit ANSI Braille rasterisation of the ATC chevron logo plus ATC block letters and a per-character gradient `atc-dsc` label, with Tool/Version/Docs info rows. Banner prints only to interactive terminals (skipped when stdout is redirected). Switches all 6 command entry points from sync `WriteHeader()` to `await WriteHeaderAsync(ct)` and reads the informational version from the assembly so the banner stays in sync with the package version.
…eck flag Check api.nuget.org/v3-flatcontainer for newer atc-dsc releases on startup, with a 24h on-disk cache at %LOCALAPPDATA%\atc-dsc\update-check.json. When a newer stable version is found, attempt `dotnet tool update -g atc-dsc` (30s timeout) and print a cyan ℹ console notice; on failure fall back to a manual-update hint. Best-effort throughout: any HTTP, cache, or process error is swallowed and never crashes the app. Suppression: `--no-update-check` CLI flag (preprocessed in Program.cs and stripped before Spectre parses), `ATC_DSC_NO_UPDATE_CHECK=1` env var, or auto-skip in CI (CI/TF_BUILD/GITHUB_ACTIONS). The flag is advertised via a new WithExample on the list command.
