## Items

### Message thread
A chronological display of messages in the conversation, with the most recent at the bottom

_Tip: Auto-scrolling to the latest message on load is expected, but scrolling up to read history should never be interrupted by new messages arriving_

### Message input
A text field for composing and sending messages, with support for multi-line input

_Tip: Multi-line input is often defined with Shift + Enter, with just Enter alone triggering the message to be sent_

### Sender identification
The sender's name and avatar displayed alongside each message, making the conversation easy to follow

_Tip: Consecutive messages from the same sender typically don't need repeated name and avatar, so grouping them reduces visual clutter_

### Timestamps
When each message was sent, using relative time for recent messages and a full timestamp for older ones

### Read receipts
An indicator showing whether the other participant has seen a message.

_Tip: Not all users want this level of visibility into their activity — read receipts are worth making optional where the product allows._

### File and media sharing
The ability to attach images, files, or links within the conversation, and show those attachments within the conversation

### Reactions
Emoji reactions on individual messages as a lightweight way to respond without sending a full reply
