tt_news
1.5.2.
1.5.3. User TSconfig
You can configure many options of the tt_news BE-form by editing the TSconfig field of the BE-user or the BE-Group this user is a member of.

Examples:
This will enable the use of "allowed categories" and adds the categories with uids 23,43,12 to this list (see section "Categories" for mre information)
options.useListOfAllowedItems = 1
tt_newsPerms.tt_news_cat.allowedItems = 35,36,37
This will exclude the categories with uids 1,2,3 from showing in the category tree in BE-forms:
tt_newsPerms.tt_news_cat.excludeList = 1,2,3
This will show only the categories with uids 4,5,6 in the category tree in BE-forms:
tt_newsPerms.tt_news_cat.includeList = 4,5,6
This will add a "Save & New" button to news and news-categories BE-forms
options.saveDocNew.tt_news = 1
options.saveDocNew.tt_news_cat = 1
This will remove the "Delete" button from the news categories form.
options.disableDelete.tt_news_cat = 1
This will set the field "hidden" in new created news articles to 0 (=visible)
TCAdefaults.tt_news.hidden = 0
If you click on the "TS" button in the right of the textarea you'll see all possible options in a pop-up window.
