FCOChatTabBrain is not about remembering chat settings of each tab!
As explained in my last post it is about changing the chat channel automatically in each chat tab to the incoming chat channel, and assist you with notifications and automatic chat tab switches (e.g. If you were not using the chat for 3 minutes and the guild chat is writing something: FCOCTB changes the active chat tab so it sjows your chosen guild chat tab and if you press the return key you can answer directly in the same chat channel the last incoming message was (as you were inactive).

Every chat tab setting is just changed and stored manually and not by FCOCTB! so if you got problems with this settings of each chat tabs channels it should be another addon's reason.
The only thing FCOCTB does with the chat tab settings (right click a chat tab and choose preferences/properties/settings) is adding new checkboxes to it so you can easily enable/disable the channels).

Btw: Chattabselector looks like another collection of this and that feature, inspired by other addons,pressed into one addon. Same author like MapPins so a nogo for me!
