Feature Request: Formatters

[happylinks]

Make it possible to show a different value in the field than get's returned.
Example:
Datepicker that shows date based on language (12/12/2015 vs 2015-12-12 vs 12-12-2015).

A plugin that I know does this is:
https://bootstrap-datepicker.readthedocs.io/en/latest/

Probably this can be combined with the getValue feature.
