30-day trajectory
Last 30 days vs. the 30 days before. Up arrows on Growth and ETV mean improvement; up arrow on Fixes share means more time on fixes (worse).
Daily performance
Daily ETV, stacked by Growth, Maintenance and Fixes.
Work-mix over time
Share of Growth / Maintenance / Fixes over a rolling 7-day window. Reads as 'where is effort flowing right now'.
Bug flow over time
Monthly bug flow attributed to this developer. The left bar (red) is bug impact this dev authored that was addressed in the given month — combining bugs others fixed for them and bugs they fixed themselves. The right bar is fixes they personally shipped that month, split between self-fixes (overlap with the red bar) and fixes done for someone else. X-axis is fix-time, not introduction-time — the Navigara API attributes bugs backward to the author at the moment the fix lands.

- 0.7ETVconsistent working progress at the bottom (set up for elapsed time + token count) (#310007) * consistent working progress with elapsed time and token usage - Always show working progress during in-progress responses - Display elapsed time + completion tokens: Working (2m 43s · 7.5k tokens) - Show past-tense on completed responses: Worked for 2m 43s · 7.5k tokens - Serialize completionTokens for persistence across sessions - Remove thinking section spinner/shimmer (outer progress handles it) - Make _usage an observable for reactive token updates - Add shared formatElapsedTime/formatTokenCount utilities * address PR review comments - Use typeof === 'number' instead of truthy checks for completionTokens (handles 0) - Fix formatTokenCount edge case where k branch could produce 1000k - Fix hasSameContent to detect isComplete state transitions - Fix timerHandle type to match Window.setInterval return type * make sure to show shimmer * shimmer only on working label, not stats Split DOM into labelElement (p, shimmered) and statsElement (span, no shimmer). The time/token stats display next to the label without shimmer animation. Also add flex layout to progress-step container for inline display. * fix padding between label and stats, accumulate tokens - Add gap between shimmer label and stats text via CSS flex gap - Accumulate completionTokens across multiple setUsage calls so token count never decreases when multiple model calls report usage * fix thinking container scroll-to-bottom Add MutationObserver on the thinking wrapper to detect child additions/removals and trigger scroll updates. This replaces the removed working spinner that previously served as a scroll anchor at the bottom of the thinking container. * show 'Finished in xs with x tokens' on completed responses - Don't gate completed summary on progressMessageAtBottomOfResponse - Don't remove working progress part for completed responses - Update text: 'Finished in 2m 43s with 7.5K tokens' * performance improvements and address some comments * address comments again + make sure we have a setting for verbose and non-verbose modes * address more comments and QOL * use font-feature-setting * better rules around diff thinking styles, rendering fixes, remove timer and token count for now * update setting name + rotating workign messages * Revert accidental policy minimumVersion bump * cleanup * remove some commented out code that we don't need yetgithub.com-microsoft-vscode · 83dc26b3 · 2026-04-17
