The concept of TabManager:
It is working like the tabChatFrames of Blizzard. Entirely rewritten from scratch.
You can create one, two or more tabmanager.
You can switch the tab position on the fly in a tabmanager
You can close a tab from the first tabmanager and add it to the second tabmanager.
Options:
You can customize the size, the backdrop and the fonts of the tabmanager, it will be apply to all tab childrens.
At the moment there are three types of tab :
Chatframe (the chatframe engine has been entirely rewritten to not use the default awful ChatFrame)
CombatLogs (entirely rewritten also)
Window
You can convert a single unit window as a TabWindows (from the explorer, use shift + right click to convert a window)
I am going to work on adding more tab type, like map, damage meter etc ...
See in the theme Sitrax how the tab manager is created.
Cheers
