I really like the new default picker option "Show link to selected workflow instance". Unfortunately it's only available for the data source "BPS Internal view". If I select a dictionary and probably a template process, it's not available.
Therefore I have to create an Internal view in addition to the automatically created dictionary data source.
For those who don't know what this option does: The picker value is rendered as a link which can be displayed in the preview window. That's a really great feature. :)
