Hints explaining values where confusion is possible

[vmarc]

Example: "facts" can refer to the number of facts in one place, and the number of routes with facts in another place. This can be confusing. Add hints to the label texts to help overcome this confusion.

Why hints? Long labels (English and other language translations) can be difficult to render on small screens, and can be difficult to understand when trying to keep the text reasonably short. A short label with a long hint can be better.
