Folders group notes by client, project, or team.
Creating one
Click ＋ New folder in the sidebar (or the + chip in the folder bar) and name it.
Filing a note
From the note: ⋯ → Folder →
From the library: right-click the note → Move to folder
Choose None to remove it from its folder
Filtering
Click a folder chip in the sidebar to filter the library to it. Click All to clear the filter. The active folder can be renamed or deleted from its chip — deleting a folder doesn't delete the notes inside it.
Folders and search
⌘K search always covers everything, regardless of the folder filter. Folders are for browsing, not for hiding things from yourself.
