I use Vista Ultimate x64 and one feature that Explorer has is really good: If you right click on a HDD/Folder one can choose New > Folder to easily create a new Folder.
Is there a way to do like this in DOpus, IE Right click > New > Folder?
I'm still not a Vista 64 user so I don't know if this will work for you, but in XP if you go to settings/file types and select the file type for All folders and configure it like the screen grab below, you should see a create folder entry added to the context menu when you have a folder selected.
By all means do what John has suggested, but the New >> Folder function you talk about in Explorer is exactly the same in Opus. However you don't get it (in Explorer or in Opus) by right-clicking on a folder, but on the background of a window showing a folder.
JohnZeman, thank you, it worked like a charm! 
Yes, i do indeed get it in Vistas Explorer. You can right click on a folder and create a new folder in Vista. This feature was added in Vistas Explorer. In Vista there is New > Shortcut and New > Folder while in XP there is only New > Shortcut when right clicking on any folder.
Thats why i miss this feature in DOpus because its a handy and useful feature and hence the reason why i asked this question.

Vista's Explorer adds it in the folder tree but not the file display, FWIW.
