In the former version, I can create a new document using an existing template with the following procedure:
File - New - Templates. This displayed a dialog for selecting template to be used.
In this version, File - New - Templates displays Template organizer dialog, and I found no way to use the selected template.
Using left or right mouse button or enter button has no action. Selection does not remain. I mean, after I clicked on a template and move the mouse from this template to another, the selection disappears.
