The navigation column has three views, labelled **All**, **Unread**, and **Mentions**. The number beside **Unread** is how many conversations need you. The number beside **Mentions** is how many mentions are waiting for you across those conversations.

The two numbers count different things on purpose:

- **Unread** counts rows. A conversation is counted once, whether it holds one new message or two hundred. Its full wording is **{{count}} conversations with unread messages**.
- **Mentions** counts mentions. Every mention in every counted conversation is added together, including mentions inside threads. Its full wording is **{{count}} unread mentions**.

Every conversation with a mention is also unread, so the **Unread** view always contains the **Mentions** view.

Both views are flat: no channel groups, no sub-channel nesting, and no thread rows, so one row is one conversation. Both are scoped to the destination you have selected, so a Space's numbers cover only that Space.

## What each row shows

A conversation row shows a number only when it holds mentions. Unread without a mention shows a marker rather than a count. Displayed numbers stop at 99; above that the row's own description says 99 or more rather than an exact figure. A parent channel rolls its sub-channels in and says so: **{{count}} unread including sub-channels**.

## What muting changes

Muting a conversation drops its unread count to zero, so it never appears in **Unread** and never carries an unread marker. Two things survive muting: a mention still counts, and a conversation you marked as unread yourself still stands out. A muted row with unread but no mention reads **Muted; excluded from roll-up**.

## Marking things read

Reading to the bottom of a conversation marks it read on its own, as long as the tab is in front and the window has focus.

To do it by hand, open the context menu on a conversation row and choose **Mark as read**, or **Mark as unread** to put the marker back. Threads carry the same pair. **Mark all as read** is on the Space menu beside the Space name and clears everything, then returns the view to **All**.

## Empty views

- **No unread conversations right now.**
- **No conversations with mentions right now.**
