Option to disable remember open chat windows
Bug description
It would be nice if the behavior added on by ticket #3803 (closed) was configurable. Honestly I read the description, but for me the feature isn't useful at all, and since I have gajim on autostart, I always get some popped up windows at boot, that I always close.
Even if it was only an ACE option, like setting opened_chat_controls to "no" or 0 would be enough.
