Your workflows have changed with AI. How about your setup?
Physical controls are back. Take the new Logitech MX Keypad, now directly integrated with the GitHub Copilot app.
This experience allows you to run agentic workflows with control, map a repeated prompt, start or resume a session, and help you stay in flow.

Even when the end-to-end tests pass, I sometimes want to see a feature working before I approve a PR.
The GitHub Copilot app lets me watch my agent run tests, build the app, and check a filter change in the built-in browser canvas.
I can verify the behavior without leaving the app or switching windows. Here's a quick walk-through. 👇

As low-quality contributions increase across open source repositories, more contributors should have the tools to help manage repos.
Users with triage, write, maintain, or admin access can now archive PRs.

Approvals are now retained for Stacked PRs after stack rebases ✅
Whether you use the "Rebase stack" button or partially merge a stack, as long as the diff doesn't change, PR approvals will be kept even if you have "dismiss stale approvals" turned on

After introducing PR limits, we heard from maintainers dealing with a flood of draft PRs.
You can now turn on “Count draft pull requests toward the limit” to include drafts in your repository’s limit.
What other controls would help you manage contributions?

Any “is the user interacting?” check has to distinguish real user input from scrolls caused by your own side effects.
One bug that held us back was “don’t correct while you’re scrolling.” It was a timestamp guard, and our own programmatic scrolls refreshed it.
Toggle the sidebar, and the diff pane changes width. Wrapped lines reflow, and the surface emits a small scroll as it settles. The guard read that as your input and skipped the correction meant to keep your place. The file you were reading drifted off screen.

What we shipped is a recurring measurement pass, gated on idle and scoped to roughly 2400px around the viewport. Mounted blocks are ground truth. Observers normally only flag a block for the pass. They don’t write heights themselves.
There’s one exception: a visible block resizing because of the user’s action can apply one synchronous correction before paint. That keeps the comment and code below it moving together without reopening the feedback loop.

For the first design, we gave every dynamic block a ResizeObserver that wrote measured heights back into the layout.
We built it, then rejected it. An observer that writes a height back into the layout it’s watching can retrigger itself, and the cost grows with every mounted block.

A code row is a line at a known height. You can compute the whole geometry up front and never have to correct it.
Comments don’t have a predictable height. So we stopped forcing one geometry to serve both, and split the document into two independent height domains.
