9.4.0 — Confetti, from a key, a merge or Settings

A snapshot as of 9.4.0 (released 2026-10-08). It will go stale as the app moves on — that is expected, and the living reference is the guide each section links to.

New features

Confetti

A celebration over the whole page: party poppers from the bottom corners, fireworks, cherry petals, paper rain and balloons. One press is a show — it comes in waves for several seconds, and mixes three of the styles you allow, picked at random (#2929). Confetti arrived in 9.3.0 without a word about how to use it; this page is that word, and 9.4.0 adds the box in Settings. It never gets in the way: it takes no clicks, and if your system asks for reduced motion, there is none.

There are four ways to throw it:

1. Try it now. Settings → Theme → Confetti → Try it.
2. From the command palette. Open it (your command-palette key, or the toolbar’s Commands button), type confetti, press Enter.

3. From a key. Bind the confetti action in Settings → Keyboard shortcuts, or write it in the config:

   { "keymap": { "confetti": "Cmd+Shift+u" } }
   

   Pick a combination your browser does not keep for itself; the shortcuts page warns about the ones that never fire. The key works on every screen, not only the terminal grid.

4. By itself, when something happens. Tick the events you want in Settings → Theme → Confetti. None are on until you say so, and the same event within a few seconds is one celebration:

   Event	When it fires
   A pull request you were watching is merged	a cell was on the PR and saw it turn merged — not for a PR that was already merged when you opened the cell
   An agent finishes a turn	every turn, so it is a lot; try it for an afternoon before leaving it on
   A Run command ends without an error	exit code 0

There is one more, and it is in no menu: press up up down down left right left right b a while no terminal or text field has the focus, and every style is thrown at once.

More: Confetti, Keyboard shortcuts.

What looks different

• Settings → Theme has a Confetti box, under the Playful effects tick (#2933):
  • one tick for each style. At least one stays ticked — the last one is greyed out — because an empty list would be read as every style;
  • one tick for each event that sets confetti off by itself;
  • a Try it button.

  Ticks save the moment you click them, with no restart. If the save is refused, the tick goes back.

  

Under the hood

• Nothing changes unless you tick something or bind a key; confetti is off for every event until you ask.
• A hand edit of config.json needs a server restart and a tab reload; the ticks do not.
• The feature list now names the confetti action (#2931). Nothing needs doing.

How to tell you have it: Settings → Theme shows a Confetti box with a Try it button, and pressing it throws confetti over the page.
