These should get Appearance slots working if you have ManicUI. Be sure to have updated the fishing updates too (couple of posts before this - bascially the ManicUI-Quests.xml).
Steps to update:
Take a backup of the following files in the <Vanguard Base>\VGUIAssets\Shells\ManicUI\Windows Directory.
Manic-Character.xml
Manic-Inspect.xml
Replace those with these and relaunch your client.
PS: I heard by new windows available for using Enchantments and it had something to do with the UI. Can someone give me screenshots and pointers to these enchantment windows and thank you.
