Thank you for your interest in ACE for XenForo! It is comprised of two parts:
AC.UI - a theme centered around a simple and performant design
Feeds - an add-on that allows filtering of dedicated feeds
ACE for XenForo Terms:
ACE for XenForo is in beta and will not have support. If you are in need of support, you can get it through our Resources subscription.
We recommend testing first and backing up your install before moving to a production environment. Emergency support is not guaranteed if it is put on production.
AC.UI heavily edits some add-ons (including Feeds and XFMG) so there may be compatibility issues between versions.
We would appreciate knowing about any bugs, so please share them here.
Options that AC.UI utilize is also covered within its documentation here.
