Toast
The result of a person's own action, with Undo: a 44 tall smoked pill at the bottom centre, one at a time, arriving on settle and leaving on release. Built on Base UI Toast.
Use it for
- What an action did, with Undo: "Moved 3 blocks", "Ticked · wrote [x] into the text", "Pinned as a live region · it updates as you write", "Correction remembered · for this exact text".
- An error that needs attention (it stays until resolved).
Don't use it for
- Recognition. The surface never toasts, badges or sounds for what it recognised.
- Anything a person must read later, or several messages at once. One at a time.
