When training the advanced numbering patterns in the serials module it's always confusing to the participants that in order to get "January" written out in a pattern, you have to use 0. The same is true for days of the week or seasons.

It would be nice if we could change the GUI to either allow using 1 for January and the like (still storing 0) or by offering a pulldown that allows you to select "January" and others depending on the formatting value selected for the pattern. This would have to be an API/Ajax call, that reacts on changes on the formatting pull down and possibly also take the Locale into account.
