In a SilverLight View Flow there were the features as follows:

• Summary dialogs which open by clicking on the respective activities (Process Summary and Activity Summary dialogs).
• Event Details dialog which open by clicking on the event.
• Comments tab, Attachments tab.

K2 Five Development team has confirmed that this functionality does not exist for Version 1 of the new Workflow Designer, however they will be implementing this functionality for a later release or update of K2 Five.

I suggest to implement the Summary and Details dialogs in the next version of the new Workflow Designer.
