Emojis next to a Trail name are easier to spot than text. Most people end up with a small visual code without ever planning it. A folder for projects, a coffee cup for personal, a screen for work. The sidebar starts reading at a glance instead of word by word.
Adding an emoji or icon to a Trail or page
Click the blank square next to a Trail or page and pick an emoji from the picker. Same square removes it.
Or right-click the Trail (or click ••• next to it) and choose Set Icon.
The system emoji picker
If you’d rather use the macOS or Windows emoji picker:
Menu > Edit > Emojis and Symbols opens it.
