A custom stylesheet that makes Slack look like something in between 'Clean' and 'Compact'. For use with Sylish, a Chrome extension. Could also work with similar extensions in other browsers but I have not tested them.
Note: Your Slack message layout should be set to 'Clean'.
Create a new rule in Stylish with these settings:
- Applies to URLs on the domain: slack.com
Then paste the code from the .css file in this repo into the code section. Set as enabled and save.
