Think about making category not global anymore
It would make sense to be able to create (and use) categories in the context of a website, and not having them global to whole install altough they may be created at any place and not only on the real root of the TYPO3 install.

Thank you for taking care. Related or the same as #72961
TCEFORM.pages.categories.config.treeConfig.rootUid = 1
works with category and children
TCEFORM.pages.categories.config.treeConfig.rootUid = 1,2,3
works only with cat 1 and children
In TYPO3 7 none of this TCEFORM works.
