Comment 26 for bug 206547

I strongly disagree with opening windows automatically by default, It breaks all indicator applet idea and in my humble opinion current way is the best (give indication that you need to give attention to conversation. If you can't then you don't have tens of windows lingering open in the background). Popup windows always have been bad stuff, and I don't see any real reason to enable it by default just because of legacy of IM clients. Option will be available and that's nice (thanks to Guillaume and other devs). But I think it should be left as it is.

It could be enabled when accounts are imported from Pidgin or some other IM client, for example.
