@Vish0007 To create this screenshot I created 3 applications called
`unhealthy`, `healthy` and `unknown` so it's just a coincidence that the name
has the same value as tasks health. When I fix all issues I'll prepare gif to
present healthy is available in all places and I'll use more generic names in
order to avoid confusion. ---
