To show your saved objects in the preview window is also very easy to manage. Let's say you have saved your newly created object in a subfolder called OBJECTSINSIDE(or any where else)
Close Vue.
Go in the folder where you have saved your new objects that doesn't show up in the thumbs. Delete the file called "object.prv". Then open Vue and click the OBJECT icon. Look at the folder where you have saved the object (in this case INSIDE) and you will see it:-).

Some more tricks if you need, just ask:-)

and: no problem if you delete object.prv. Vue will create a new one:-)
