Yana and me have plans to improve the usability of the multi user chat support. Maybe you noticed, that if you want to create a multi user chat, you cannot just simple add/invite someone to a singlechat like it is possible in so many other IM apps. Instead of that you have to create a multi user chat explicitly first, and then you can invite others to that multi user chat. We want to change that, we thought of a simple invite button in the single chat window.
That sounds not very hard to get this done, but its not that easy to do that. The problem is that internal there is a difference between a single chat window and a multi chat window. For single user chats we use MetaContactChatPanels and for multi user chats we use ConferenceChatPanels. So if you want to switch between a single and a multi user chat, you have a "big" problem.
Now we think about merging those two Panels to only one Panel, that would resolve our problem and would be a logical step, because when you look at the single chat window, it looks like it is supposed to became easily a multi chat window.
Because this would be some kind of a bigger change, we want to discuss this with all the devs. So please tell us what you think about it.
