Designer Pro and Photo & Graphic Designer have included 11 plug-ins including popular choices from Mehdi, Av Bros and Redfield and (in V8 and later) 35 plug-ins from Magix. In v9 we added a further 11 MAGIX plug-ins. In v10 and 11 only we included Red Giant's PhotoLooks 2 Plugin.
The full set is not included in the trial download, only on the purchased version. Once you have unlocked your program go to Help > Download Content to download the content installer which will install these additional plugins.
The plug-ins are accessed by selecting an object and then clicking on the Live Effects Tool (Ctrl & F5). Then click on the 'New' button in the Live Effects InfoBar and select the effect you wish to apply.
