Starting to fix the new group field.

When you put a  "slides" element into a "group" element, so a user can create multiple slideshows, the group gets automatic the label of the last slide name/title created in this group. But when you have mutiple slideshow and in some of them have the same titles in the last slider, their groups will have all the same name. It would be nice to have the opportunity to put a field into the group (group-title), so the user can rename the group himself.

thx
