Thermometer as field widget for core number fields

This is a neat idea! Do we think the "maximum" and all other config should come from the field formatter settings? So each time you use the formatter, you would choose the locale/currency, goal, etc?

If you want to use it as indicator for let's say funds raised:
It would make sense to have views support. Then you could use views aggregation summing up multiple donations and format to output as a thermometer.
Very nice.

Goal on the field/view level:
You could set a goal on the field formatter. But what happens if you get more donations than that? Because in the views scenario the individual donation may be much less than the aggregated sum.
Maybe it is more clever to have an individual views formatter? I can't say.

Anyway: Maybe one doesn't specify an absolute number, but a relative one. Like what is the equivalent of the goals 100%? e.g. field formatter value: 50 000. So then you'd have Label [100% equivalent] = Value [50 000]
Then you could also display a higher amount than that and still show you have met the goal.

And the same could go with maximum.
