Hi,
for your second question. You have to set the Option "Display created" in the form configuration (Tab "Dataview in Frontend") to a value different from "Don't show" (any other value is fine).
After that you have to add "displaycreated":"true" to the parameter string.
Code:
{vfdataview}{"formid":"9","fieldlist":"created,109,110,111,112,113","display_num":"5","show_page_heading":"false","layout":"defaultnodesc","displaycreated":"true"}{/vfdataview}
For your first question. Displaying a detail link is not a feature of the vfdataview plugin. The idea behind the plugin was that you can select very specifically which record sets and which fields are displayed and that you either use the list, if you have not so many fields or the detail if you want to show many fields.
If you use the menu item type "dataview" that comes with Visforms itself you can create a data view with list and detaillink and detail. But you cannot select the recordsets as flexible as with the plugin. Maybe this is an option, if you use the vfformview plugin to display the form in a module on that data view created with a menu item of type Visforms data view.
