WidescreenTour1 is similar to RandomPosition and WidescreenShowroom presentation to some extent, it support multipe albums but not nested albums, images in an album can either be displayed in random position or predefined fixed position, a unique feature of this feature is it comes with video support and the video can be played together with other images of current album.
Another important update in UMG 6.2 is the ability to assign permissions by user name rather than role name. You can now find an option to control this behavior in "Settings" page, "Advaned Options" section, once enable it, you can manually enter the username when assign add/approve/manage/view permission.
