There are to a few web pages describing how to add custom Columns in TicketOverviewSmall - for instance http://techiesfromthecradle.blogspot.ch/2012/08/customizing-otrs-list-views.html

This doesn't seem to be applicable any more with OTRS 3.3 - the file has completely changed, as it introduces new capabilities like sorting / filtering.

Do you know of any documentation on how to add more columns on this view, specifically:

- Dynamic Fields

- Fields coming from a DB Customer Backend (for instance customer Language) 

Ideally, I'd love to be able to sort / filter them as well :)

Thanks,

Olivier
