A type folder changes the way fact titles are displayed in the various lists. When a fact is inside such a folder, to its title is being added a special string to show the type and allows you to put a custom fact icon.
#85 Infobox Permissions - max rows
Here you can define how many rows of permitted groups should be shown in the info box, before a "more"- link is suggested. The default value is unlimited.
#86 Force permission check in forms
When checked the publish button opens the permissions layer with another publish button inside. This way the user is forced to check what permissions are selected before publishing the fact.
#87 Un-seen facts show with color
if used, facts that the user has not seen yet will have this style added to their link. If nothing specified, there will be no difference in the style of the seen and the unseen facts.
