Clients
Each task can optionally have a Client. Clients represent who or what you are doing the work for.
You could use Clients to represent your actual clients in your business, different stakeholders in your job, or something more abstract like your own goals or life areas (family, health and the like).
Manage your Clients from the Things page. Each Client has a name, a colour and optionally some notes in Markdown format. Each Client has their own view, which includes the notes and all associated tasks.
If Clients don’t make sense in your workflow, you can turn the feature off in your settings.
