How it Works

Slack Channels Grouping automatically organizes your Slack sidebar by grouping channels that share the same prefix.

Prefix Detection

The extension detects prefixes by looking for the first - (dash) or _ (underscore) in a channel name.

Channel Name	Detected Prefix
dev-api	dev
dev-frontend	dev
project_backend	project
team-design-v2	team
general	(no prefix)

Grouping Example

Channels with the same prefix are visually grouped together:

Before:

# dev-api
# dev-frontend
# dev-backend
# sales-leads
# sales-reports
# general

After:

# ┬ dev-api
# ├ dev-frontend
# └ dev-backend
# ┬ sales-leads
# └ sales-reports
# general

Visual Indicators

The extension uses tree-style separators to show grouping:

Symbol	Meaning
┬	First channel in a group
├	Middle channel in a group
└	Last channel in a group

Supported Channel Types

Channel Type	Grouped
Public channels	Yes
Private channels	Yes
Direct messages	No
Group DMs	No

Direct messages and group DMs are intentionally excluded from grouping to keep your conversations easily accessible.

Zero Configuration

Simply install the extension and it works automatically. No setup or configuration required.
